Bug description

I updated my osu-lazer version from 2026.804.2-lazer to 2026.921.0-lazer hours ago.
When I connected my mouse with 2.4G, and open the app, I found that my mouse cursor can't move. But when I disabled high-precision mouse mode, I can move my mouse.

It is likely that #31441 has worsened.

In the latest version, absolutely no input is recognized anymore in relative mouse mode.
It was so problematic that I investigated a bit, and it appears to be an issue on the SDL side.
In the SDL Java source (org.libsdl.app.SDLGenericMotionListener_API14.onGenericMotion), there is no case handling for events in relative mouse mode, so they are apparently being dropped.
ACTION_DOWN, ACTION_UP, and ACTION_MOVE (not ACTION_HOVER_MOVE) are missing.

This is a bit disingenuous of me, but since I have absolutely no knowledge of SDL, I would like someone with more experience to conduct further research...

I was able to restore normal operation by hooking with Frida.
