When I have Brave browser open (one instance and multiple instances) and do an ALT-TAB, the icon does not appear. It is blank:
Ubuntu Budgie 20.04.3
How have you installed brave?
I.e. is this a flatpak, snap or deb install?
I went through the Software icon. I think it might be a snap.
hmm - I’ve installed the brave snap on 21.10 ubuntu budgie - alt tab shows the brave icon ok.
Did a reboot and now it works.
