I think that the issue only appears when `Document`>`Line Wrapping` is activated.

I can't reproduce my own report. But it happened once. And I made a screenshot. And it happened always when I was using Geany 1.39 by PPA with the plugin Geany Preview and with two lua-scripts.

I can't reproduce https://github.com/geany/geany/issues/2559, because in my case in the moment where line numbers are visible, then the issue does not exist. I can't reproduce https://github.com/geany/geany/issues/1521. And I can't confirm the description. In my case the issue didn't happen when I was typing. The issue appeared when I was scrolling.

If you can confirm it with Geany git version or latest Scite then please report to Scintilla referencing this issue.

I don't know how to install Geany git version or latest Scite. But I will report it to Scintilla.

One comment on sourceforge.net is:

I have seen this rarely. A possibility is that buffered drawing is on and that an error in the drawing code causes return to the by-line loop without any new drawing into the buffer bitmap. Then the previous line's image is drawn onto the new line. You could turn off buffered drawing (SCI_SETBUFFEREDDRAW) if it is on to check this - I don't know if Geany supports changing this setting.

Another possibility is that there is a bug in the line wrap positions so that the same subline is present twice.

Is there a possibility to turn off buffered drawing (SCI_SETBUFFEREDDRAW) in Geany?

You could comment out the ifdefs [here](https://github.com/geany/geany/blob/5cdfe35cf26ca6935eddc652cceb799e0cbad142...) so it happens on all platforms and GTK versions to see if it fixes it.

Do you mean like this? ``` /*#ifdef GDK_WINDOWING_QUARTZ*/ /*# if ! GTK_CHECK_VERSION(3,16,0)*/ /* "retina" (HiDPI) display support on OS X - requires disabling buffered draw * on older GTK versions */ /*SSM(sci, SCI_SETBUFFEREDDRAW, 0, 0);*/ /*# endif*/ /*#endif*/ ``` And what are the disadvantages when it is turned off?

Almost, leave the SSM line uncommented, thats the one that turns it off.

To avoid misunderstanding: Is the following correct? ``` /*#ifdef GDK_WINDOWING_QUARTZ*/ /*# if ! GTK_CHECK_VERSION(3,16,0)*/ /* "retina" (HiDPI) display support on OS X - requires disabling buffered draw * on older GTK versions */ SSM(sci, SCI_SETBUFFEREDDRAW, 0, 0); /*# endif*/ /*#endif*/ ```

Can't reproduce with latest Git Geany. Can you try that, the Scintilla has changed significantly.

Today I reinstalled Lubuntu 22.04, and I did ``` sudo apt update sudo apt dist-upgrade sudo add-apt-repository ppa:xiota/geany-plugins sudo apt update sudo apt install geany-git ``` In Geany I did only this: I activated in both txt-documents: Document>Line Wrapping.

The issue is still there (the stretched cursor is just before the word github):


Please post the lines of Help->Debug Messages that list Geany version, GTK and Glib versions.

``` 12:20:14.967704: Geany INFO : Geany 1.39, unknown 12:20:14.967743: Geany INFO : GTK 3.24.33, GLib 2.72.1 ```

In Geany I did only this: I activated in both txt-documents: Document>Line Wrapping.

Did you make the changes discussed [here](https://github.com/geany/geany/issues/3271#issuecomment-1236121036)?

Ahh it wasn't a source repository, so I guess you can't change it.

Why not build from the [nightly tarball](https://download.geany.org/geany_git.tar.gz) in accordance with [these instructions](https://github.com/geany/geany#installing-from-a-release-tarball)

I'm just a software user. I never built a software before.

Oh, ok, for some reason I thought you had built Geany before, so thanks in advance.

You will need some tools, I'm not sure of the commands on Ubuntu, I use Synaptic to install them, `build-essential` and the `libgtk-3-dev` development packages. Don't bother with the tools to build the manual, see the extra option on the `configure` command below.

Ok, create a directory in your home, say `geany_build` and untar the nightly tarball there. I think it will create a directory called `geany_git` so cd to it then:

``` ./configure --prefix=/the/full/path/to/home/geany_build --disable-html-docs make install cd ../bin ./geany -c ../config ```

This will build an isolated version of geany and run it with its own config, so it won't touch your system install or your user config, so you can play to your hearts content :-)

And just delete the whole directory tree `geany_build` to remove it when done.

I suggest you build it from the tarball first and confirm the problem still occurs, then comment out the parts of `src/editor.c` using an editor, might I suggest Geany (your newly built version ;-) run `make install` again and see if it makes any difference (don't forget to cd back and forward to the right directory `geany-git` to run `make install` and `bin` to run `./geany -c ../config`.

If you use `geany_git.tar.gz`, you must call `./autogen.sh` before `./configure` (for release tarballs this step is not required).

As mentioned in the [README](https://github.com/geany/geany#using-autotools), you need to install a few build time dependencies:

autopoint, automake, autoconf, libtool, gettext

The GLib development files already have been installed as dependencies of `libgtk-3-dev`.

You should now be able to run `.autogen.sh`.

Not sure why it doesn't exist for you, I just checked it *is* included in https://download.geany.org/geany_git.tar.gz.

Ah, sorry it was ./autogen.sh

I forgot the slash.

How can I remove the geany version that I downloaded with `sudo apt install geany` to be sure, that the new geany is running?

Or just `apt remove geany`

I reinstalled Lubuntu, but this time the installation of Geany nightly tarball failed. This is what I did: this is the step-by-step-description how to install Geany from the nightly tarball in Lubuntu 22.04:

``` sudo apt install build-essential sudo apt install libgtk-3-dev sudo apt install autopoint sudo apt install automake sudo apt install autoconf sudo apt install libtool sudo apt install gettext ```

(Note: change the expression USERFILE to user name)

in /home/USERFILE create the file `geany_build`

then download the nightly tarball from https://download.geany.org/geany_git.tar.gz

then untar the nightly tarball called `geany_git.tar.gz` in the file `geany_build`

so, in the file `geany_build` there is the file `geany_git`

then in the terminal go to the content of geany_build by the command `cd geany_build` then in the terminal go to the content of geany_git by the command `cd geany_git`

then do this in the terminal: ``` ./autogen.sh ./configure --prefix=/home/USERFILE/geany_build --disable-html-docs sudo make make install cd ../bin ./geany -c ../config ```

Already for `sudo make` there seemed to be a problem: ``` sciwrappers.c: In function ‘sci_set_lexer’: sciwrappers.c:679:9: warning: ‘LexerNameFromID’ is deprecated [-Wdeprecated-declarations] 679 | ILexer5 *lexer = CreateLexer(LexerNameFromID(lexer_id)); | ^~~~~~~ In file included from sciwrappers.c:38: ../scintilla/lexilla/include/Lexilla.h:91:47: note: declared here 91 | DEPRECATE_DEFINITION const char *LEXILLA_CALL LexerNameFromID(int identifier); | ^~~~~~~~~~~~~~~ ```

And same for `sudo make install`: ``` libtool: warning: relinking 'classbuilder.la' mv: cannot move 'classbuilder.so' to 'classbuilder.soU': Permission denied libtool: error: error: relink 'classbuilder.la' with the above command before installing it make[2]: *** [Makefile:629: install-pluginLTLIBRARIES] Error 1 make[2]: Leaving directory '/home/t/geany_build/geany_git/plugins' make[1]: *** [Makefile:911: install-am] Error 2 make[1]: Leaving directory '/home/t/geany_build/geany_git/plugins' make: *** [Makefile:590: install-recursive] Error 1 ```

What should I do? What did I do wrong this time?

Use sudo chown -R t:t /home/t/geany_build/geany_git (assuming "t" is your username). Afterwards run make and make install again.

Now Geany works. Thank you for your help.

The issue is still there:


Document>Line Wrapping is activated

Now there are two new disadvantages: - there is an empty line where I can't even place the cursor (between 15 and 16) - if I navigate on the keyboard with the key arrow-down from line 13 to 16, the cursor will stop at line 15 at the end of the line; even if I press again many times the key arrow-down, the cursor will not move (but navigating with the key arrow-up from line 17 to line 13, then there are no problems)


I think that all the problems are because the line stops at the right border. One reason could be that there is not enough place for the wrapping-symbol on the right side.

If you use geany_git.tar.gz, you must call ./autogen.sh before ./configure (for release tarballs this step is not required).

@eth16, I didn't know this, the point of using the tarball was to save @ralf3u installing autofools, if the nightly tarball needs the full toolset might as well have cloned git, sorry @ralf3u

@ralf3u best to report the strange blank line behaviour to Scintilla as well, it might help narrow down the problem. And looks like Neil thinks you are a developer too, giving you patches to try in Scintilla ;-)

The empty line and the two disadvantages of https://github.com/geany/geany/issues/3271#issuecomment-1236386886 occur **ONLY** if an other tab with a txt-document is right away in focus after a restart of Geany. In other words: If the tab of the corresponding txt-document is right away in focus after a restart of Geany, then there is no issue. Because of that, I think that not Scientilla is the problem, but Geany, but maybe I'm wrong.

What do you think about that?

Is that with or without the changes of https://github.com/geany/geany/issues/3271#issuecomment-1236382367?

without the changes

I doubt that the plugins will have any effect.

I could reproduce 1 and 2 every time with the plugin Geany Preview and two lua-scripts.

Thanks to @xiota, but please keep using the Geany made from the tarball, you can make changes to that.

OK.

[...] and its up to you to help Neil.

From now on I will continue to report the issue at Scintilla, so I don't need to report it twice. But I let this issue at github open till there is a result at sourceforge. If you have a better handling, just let it me know.

@elextr and @eht16: Hey, that's too complicated to work with a debugger for me. I have an alternative: I could try to reproduce it on a 15.6-inch-FHD-notebook on Lubuntu-Live-ISO with Geany installed by PPA (that uses geany-git from last Sunday), with two txt-documents. I could then upload the two txt-documents so that you could see the bug and work on it with Neil.

Are you using a 15.6-inch-Full HD-display notebook?

@xiota thanks for trying, IIUC GFX in a VM is different to GFX in a bare metal OS, so that might be why it doesn't happen, or as you said maybe its hardware specific, or it could be X11 vs Wayland specific, or maybe GTK version, so many moving parts :-(.

Like you I can confirm I saw the repeated lines a while ago and then it went away, but I also can't reproduce it now, or the end of line thing.

@ralf3u do you have Geany full screen? If not the display size and resolution shouldn't matter. If you are doing it full screen please try it in a window sized so the end of line falls at the edge.

The step-by-step-description is now online how to see the bug:

`LIBGL_ALWAYS_SOFTWARE=true geany`: the issue is there

@xiota

What resolution are you using on each computer?

Today I wanted to upload the data of the 15.6´-FHD-notebook. But the bug could be reproduced (https://sourceforge.net/p/scintilla/bugs/2349/#498c). Do you still need the information?

Today I saw a short line twice in the Geany-git by PPA that was built around 10 days ago, so the issue for short lines is still there. But I couldn't reproduce it. If I can reproduce it, I will mention it here and I will open a new issue at sourceforge.net.

When short lines starts to appear twice, then the top line of the editor is completely red (from the left border to the right border of the editor) for some seconds. A saw this behavior many times in the past.

The issue of short lines and last lines of paragraphs disappears when buffered drawing (SCI_SETBUFFEREDDRAW) is turned off (https://github.com/xiota/geany/issues/2#issuecomment-1249414773 and https://github.com/xiota/geany/issues/2#issuecomment-1249501316).

To my knowledge, I have not turned off SCI_SETBUFFEREDDRAW in my PPA builds. The recent build you refer to has removed for testing the `IS_WIDGET_MAPPED` check in `ScintillaGTK.cxx`, as suggested in [this comment](https://sourceforge.net/p/scintilla/bugs/2349/#bb06) on the scintilla bug report.

I just opened a new bug at sourceforge: https://sourceforge.net/p/scintilla/bugs/2354/

I don't understand why a new bug report is necessary.

Are all of the line duplication issues resolved by removing the `IS_WIDGET_MAPPED` check?

Unless scintilla devs asked you to open multiple bug reports, the problems seem closely related enough to fall under one report, especially if a single patch addresses all of them.

The bug was fixed today at Scintilla (https://sourceforge.net/p/scintilla/bugs/2349/?page=1#e800).
