Bug ID: 428559
Summary: Bad ".desktop" file can easily screw up all gtk icons
Product: kwin
Version: 5.19.5
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: decorations
Assignee: kwin-bugs-n...@kde.org
Reporter: quwenruo.bt...@gmx.com
Target Milestone: ---
SUMMARY
If installing a specific game (*) using steam with proton, proton would create
a corrupted desktop file ".desktop" (exactly the name), to corrupt all gtk app
icons used in decoration and "big icon" alt-tab switcher.
The offending game is https://store.steampowered.com/app/1372300/Iwaihime/
But since the cause the ".desktop" in .local/share/applications, it doesn't
need the game to do the trick.
STEPS TO REPRODUCE
1. Create file ".local/share/applications/.desktop" with whatever icon you like
2. Check the icon of the window decoration of any running gtk applications
3. Check the icon of "big icon" alt-tab window
OBSERVED RESULT
Most GTK applications get wrong icon from the ".desktop" file.
EXPECTED RESULT
GTK applications still follow their original icon.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch
KDE Plasma Version: 5.20.2
KDE Frameworks Version: 5.75.0
Qt Version: 5.15.1
ADDITIONAL INFORMATION
Maybe it's a bug in gtk icon cache? But strangely I only found the following
icons get affects:
- GTK app icons in window decoration (if enabled)
- GTK app icons in big/small icon alt-tab task switcher
QT applications like konsole, dolphin doesn't get affected.
And of course, with that ".desktop" file renamed, everything comes back to
normal.
