I am also experiencing this, with the same error logs.

Some added context: As strange as it may be, it seems to happen mostly when I am in game when I flick the cursor to the edge of the screen (any direction)

boombel commented 1 month ago

Same issue here, crash observed on main. It crashes when moving the mouse cursor to the bottom right of the screen (very inconvenient for playing strategies, auto restart is very helpful). Host: integrated AMD, guest: AMD 6800S.

Credit to @D0ot for finding and fixing this.
