Using Discord while playing Hunt Showdown and if I alt+tab away from the game into Discord to volume adjust, unmute myself or someone else, the left clicks are going to the game and causing some not so great misfires. Anyway to prevent the left click from propagating into the game window?
Using KDE + Wayland and Discord Flatpak if that effects it at all.
I'm in a similar boat. I've got a bunch of small Wayland niggles, but I'm waiting to investigate them until after I switch to Tumbleweed when it gets Plasma 6 (I'm currently on Kubuntu).
I thought that stuff like this couldn't happen on Wayland by design but maybe that's only true for keyboard inputs. Unfortunately, I have no idea how to help you but I hope that this information was at least useful to someone who knows more than me.
