Game behaviour

Bug description

Probably related to ppy/osu-framework#6181
After clicking on any button, the game freezes until I click or press any key again (A-Z keys seem to not unfreeze) . Seems to happen at random

I have tried turning off high precision mouse, the issue still kept happening

Same here, clicking on anything using mouse freezes the game for a second.
Though it unfreezes itself automatically in my case, nothing I do unfreezes it until almost a full second passes away.

However, I shall note that I updated osu! at the same time I updated from GNOME 46 to 47... just to keep that in mind.

Using Fedora 41 / GNOME 47.

Edit: seems far less noticeable when the system's under low load, but it's still there. Doing the same interactions with Keyboard doesn't cause issues (i.e. i can play just fine, but navigating stuff with mouse is a bit meh)

Could you take a video once again with graphs (Ctrl+F11 twice)?

Here's the video with the graph

Setting Graphics > Threading mode to Single thread seems to not cause freezing. Ironic....
Also, SDL_VIDEODRIVER=Wayland OSU_SDL3=0 env vars fix this entirely.... Yet another SDL issue

[hwsmm]

How about SDL_VIDEO_DRIVER=wayland without OSU_SDL3=0?

[vextrinct]

That also fixes it, no more freezing

Still happens even after the latest update that disabled SDL3. Neither single-threaded mode nor the env vars mentioned above seems to affect it.
Trying different graphics backends (Vulkan (experimental) and OpenGL (experimental)) doesn't do anything either.

Seems to happen on most clickable things, but not all of them.. this includes top bar, main menu, song select, preferences. Can't notice it in song loading screen's options, nor within gameplay (if you use mouse to click).
Doing the same stuff with the keyboard is smooth, so it's not a blocking issue, but very weird.

Note that I'm using the Flatpak version.
