Cursor stuck

[Fleische]

When I launch the game, the mouse cursor seems to think it is on a much smaller screen than it actually is. When I move it far enough to reach the right or bottom of this imaginary screen it springs back to the top left and now will move even less far.

I can work around thiss to an extent because fortunately all menus are keyboard navigable too, but IDK if this will cause gameplay issues.

By default the game launches in 2048x1152 but even at 640x480 the mouse box is a bit smaller.

Attached is my hpl.log (why all the warnings and errors).
