been a while since I used kde & wayland, but I remember there being something in the Plasma settings -
random redditor said "Go under "KDE Settings->Applications->Legacy X11 App Support" and click to allow keylogging for all keyboard keys", I think this was it. Had discord (running in xwayland) accepting my global hotkeys with no problems
Discord definitely supports this, I’ve seen meme videos grow vertically from 16:9 to probably 400:9. Pretty funny though
