/home/mruckman/.config/BraveSoftware/Brave-Browser/The broken icon seems to be a symptom of Ubuntu and M1.
I just found that you can work around this issue by disabling Wayland in Ubuntu and use the standard Xorg server that was the default in versions prior to 22.04. There are full instructions here, but you can simply edit the file
sudo gedit /etc/gdm3/custom.confand uncomment the line
#WaylandEnable=falseAfter a restart the gear icon goes away, focus stays in the window you where using when switching desktops, and shared clipboard still works.
