Osu sometimes won't open after SDL3 was enabled

[cosstab]

After updating to Osu Tachyon 2026.512.0 on Arch Linux, I first noticed that I couldn't click with my tablet (as mentioned in #6749), so I restarted my PC and, after that, the game wouldn't even open multiple times in a row. This seems to happen sporadically now, the game opens most of the time.

This doesn't seem to happen when I set OSU_SDL3=0.

I tried switching to KDE and the problems disappeared. It seems they only happen in GNOME.

Edit: other people seem to have Wayland related problems with KDE Plasma and COSMIC.

Your logs show that you're using an unofficial distribution channel/version of osu!. Please verify that the problem occurs on the official AppImage available at http://osu.ppy.sh/home/download.

Right, I already did that before creating the issue, with the same results. I should have mentioned it.
For clarity's sake: now I'm running Tachyon 2026.525.0, downloaded from the official web.

I checked the system logs and I get this every time I open the game:

gnome-shell[2713]: Buggy client (osu!) committed initial non-empty content without acknowledging configuration, working around.

And this when I close the game (without crashing):
