I stumbled across an issue with icons. They’re inconsistent across DE.
Firefox Developer Edition’s icon looks like regular Firefox in ‘Window Buttons’ plugin as well as in ‘Alt+tab’ preview. Similar issue with VSCodium - different icons.
Plank and Whisker Menu show correct icons.
I’ve tried changing icon themes in settings->appearance but it doesn’t seem to change those icons (even after reboot).
I’ve looked for that green vscodium icon on my machine but the only icon i’ve got is the white/blue one.
I’m using Papirus-Dark icon theme.
Any advice ?
