Mouse events regression in 0.29.12+ on X11

[rafalh]

Testing new the Bevy version 0.13 on Linux I encountered a mouse-look camera regression. I tracked it down to release 0.29.12 of winit.
On both videos I am trying to move my mouse horizontally and the only difference is winit version.

winit 0.29.12

winit 0.29.11

In the first one horizontal movement is very slow and generally mouse moves in a diagonal motion. In the second it works as expected.
I think it may have been caused by 3d4c534

Likely related to bevyengine/bevy#12198
