Thanks a lot for this great piece of software I've been with for so long now :)
Since upgrade from 1.38 to 2.0, font rendering seems to have changed, precisely horizontal spacing?/ligatures? between letters has increased, and seem to be unpar with other gtk app using same font+size (first noticed as when activating document wrapping, document displaying less lines within viewport)
checked gtk/pango/fontconfig stack against both debian stable/bookworm + unstable/sid, and without any relevant clue I could report from dbg logs
Looks like Scintilla rounding of fractional positions to integer pixels has changed for your system with [unspecified] font and [unspecified] size on a monitor with [unspecified] DPI with [unspecified] display server and [unspecified] GFX driver.
See also #3738 where that causes extra gaps and misalignment between 1.38 and 2.0, with the fix there (setting `pango_context_set_round_glyph_positions` to TRUE) both 1.38 and 2.0 produce exactly the same width text for me. But as @nyamatongwe pointed out setting that has other negative effects, YMMV.
The problem in #3738 is reported (by a bleeding edge Suse Tumbleweed user ;-) to go away with Pango 1.51.1, so maybe when that is in Debian you could re-check to see if it fixes this as well.
Hack Regular font size 13 at 96 dpi with xorg and i915 thanks for pointing to #3738, will try pango_context_set_round_glyph_positions as its negative effects won't affect me while waiting for Pango 1.51.1 in debian (and will recheck then)
Thanks and thanks for pointing me to #3738 Hack regular font 13 at 96 dpi with xorg and i915 here will try `pango_context_set_round_glyph_positions(pcontext, TRUE)` as I should not be affected by #3111 as I don't use chinese while waiting (or maybe reporting it in debian to push it) for Pango 1.51.1 then recheck
then recheck
Don't forget to take the TRUE out first, at first I didn't ;-P
just to confirm setting it to TRUE fixed it for me too hereafter my 99_pango_context_set_round_glyph_positions_true.patch added to debian series ``` diff -Naur a/scintilla/gtk/PlatGTK.cxx b/scintilla/gtk/PlatGTK.cxx --- a/scintilla/gtk/PlatGTK.cxx 2023-10-19 18:09:27.000000000 +0200 +++ b/scintilla/gtk/PlatGTK.cxx 2024-01-25 07:08:24.603457827 +0100 @@ -76,7 +76,7 @@

thanks again, I will no forget to revert it (re-installing vanilla debian package one) when pango 1.51.1 in
