Raw Input not capturing mouse (on wayland)

[Anti-Apple4life]

When I enable raw input on the osu client, raw input is enabled, but the mouse moves out of the osu window, as the window is not capturing it.

Open ~/.local/bin/osu-wine with any text editor, and change WINE_BLOCK_GET_VERSION=0 to WINE_BLOCK_GET_VERSION=1. @peppy

As he said, it's due to osu!'s behavior once it detects it's running under Wine, along with a bunch of other stuff.

For the time being, the fix is to set WINE_BLOCK_GET_VERSION to 1 so that the game detects it's on Windows and behaves normally. Revert to 0 if you notice any error with it!
