On Wayland, the Telegram Desktop app window borders and header look totally out of place, is there a way to make it look like it does on Xorg ? I’ve been searching for a solution for this for a long time now but couldn’t find one. Ugly Telegram image bellow:
You should go to (in telegram) to Settings/Advanced → scroll down to “System integration” and check “Use system window frame”
Mine is GTKish on Fedora 35 with Wayland.
