I could narrow it down, but I can't explain it!
If I manually set `sTransparentMainWindow` to true, the bug does not occur.
The following check prefs it from ever becoming true because I'm non non-composited KDE: https://searchfox.org/mozilla-central/rev/919607a3610222099fbfb0113c98b77888ebcbfb/widget/gtk/nsWindow.cpp#4165,4178
If I remove the check, the bug only occurs if I manually create `mozilla.widget.use-argb-visuals=false` on about:config.
