You can clearly see it if you add this code in the event handler: 293 elif event.key == K_a: 294 pygame.mouse.set_visible(False) 295 elif event.key == K_z: 296 pygame.mouse.set_visible(True)
At the very beginning i do pygame.event.set_grab(False) then if you try to press key z to show the mouse, then mouse it, press a to hide it: you'll see the "virtual input" mode is activated. I'm pretty sure this is a bogue. Please tell me if you can reproduce it under Linux, thanks a lot!
