--- Comment #2 from alexandros.frantzis@collabora.com --- Thanks, this is known issue, see the description in https://gitlab.winehq.org/wine/wine/-/merge_requests/5264.

The TL;DR is that there was a bug in Mesa that could cause a crash when enabling this attribute, so I held off using it in winewayland. I fixed the bug in https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/28153, but the vulnerable Mesa versions are still used widely. I guess it's time to revisit, but we still need to figure out how to avoid crashing (checking against Mesa version?).

As a side note, the fact that the background is visible when an non-opaque app is in fullscreen mode is a compositor bug (e.g., see https://bugs.kde.org/show_bug.cgi?id=461063).

--- Comment #3 from lassebq.mine@gmail.com --- I see. I didn't know there were issues with older mesa versions.

By the way I'm using GNOME. So this seems more like a compositor decision to allow fullscreen transparency?
