SUMMARY Latte Git version is using Kirigami.Icons these days. I opened Latte git version under Gnome 40. The problem is that some icons are forced painted even though they should not. The issue is reproduced only under Gnome40 and not Plasma because Plasma.LibTaskmanager provides something different Kirigami.Icon.source . By checking https://github.com/KDE/kirigami/blob/master/src/icon.cpp#L309 I think lines #309-320 is the issue. In these lines if guessMonochrome() function provides faulty results then Kirigami.Icon is forced to be painted ALWAYS. To check the scenario I provided isMask:false and color:"red" and the icon was painted RED even though it should not. An icon that guessMonochrome() fails is from Materia Icon Theme the kwrite/kate icons. STEPS TO REPRODUCE 1. Use Materia Icon theme 2. Open Latte Git version under Gnome 40 3. Open KWrite OBSERVED RESULT KWrite icon is monochromatic painted even though it should not EXPECTED RESULT KWrite icon should not be monochromatic painted SOFTWARE/OS VERSIONS Linux/Gnome: Gnome 40 (available in About System) KDE Plasma Version: 5.15.4 KDE Frameworks Version: 5.81.0 Qt Version: 5.15.2
Can confirm; I was looking at this code recently myself, and noticed that it seemed a bit suspect. Would you be interested in submitting a merge request to fix it? Might be as simple as always disabling the auto-coloration behavior when isMask is false.

It is pretty clear that its creator wants a code path that will apply autocoloring automatically and it is not pretty clear how it should be disabled. My thought is that this codepath was introduced for PlasmaMobile top panel that is probably autocolored so it should be better to be fix by them because anything else will probably break their current plasma mobile implementation.
