Any #SteamDeck users using Firefox there? If you run Firefox in game mode and open about:support, what does it say under "Window Protocol"? X11 or Wayland? And maybe also check the Firefox version?
@krosylight Gamescope doesn't really handle Wayland (xdg-shell) clients. It has some very basic support, but not nearly enough to handle apps like Firefox, so it all goes through X11 over XWayland.
@dos Meaning, yours say X11? 👀
@krosylight Everyone's say X11 and always did.
@dos And yours too? Just checking...
@krosylight Which part of "everyone" is ambiguous? 😜 Yes, mine too.
@krosylight Not in gaming mode at least. It may make sense when used with nested kwin_wayland for example (which is how I usually run Plasma on my Deck), but it's useless when used directly under gamescope.
You could run gamescope with `--expose-wayland` parameter, but even then it will only work with very simple apps; definitely not with Firefox 😅
@dos Some people just reference what other people say without checking themselves, so just wanted to check that 😄
Thanks for the info about gamescope! I saw many posts about setting MOZ_ENABLE_WAYLAND (which is now the default) on Steam Deck to make it use wayland, and are you saying it's never been useful at all? 👀
