**Steps to reproduce** 1: open Geany 2: open two different txt-documents, both very long, so that only two tabs exist 3: close Geany 4: reopen Geany (result: the txt-document what is in focus is shown correctly) 5: switch to the other tab where the other txt-document is located
**Result** The problem is that this happens only sometimes and one need to scroll to look for double lines (I did all the steps above about 20 times): The txt-document is not shown correctly. Some lines of the document are shown 2x. What is also strange is that the cursor is stretched over two lines. Once I saw lines not only 2x but 4x.
**Remark** This is really a big issue. It started some weeks ago. I thought that it was caused by the plugin Geany Preview or by using Geany by PPA (https://github.com/xiota/geany/issues/2 and https://github.com/xiota/geany/issues/3). But today I reinstalled Lubuntu 22.04, I installed Geany, I installed geany-plugins, I installed some software for kvantum for having the dark mode, and I used Sleepy Pastel as colorschemes in Geany. And then the issue was there again. I can't remember that I saw this issue in Geany 1.37.
