[pygame] Re: Problem with mouse going back to the center of the screen

[SurferIX <olivier.pons@xxxxxxxxx>]

Ok you were right.
Here is the summary: with Linux:

pygame.event.set_grab()
pygame.mouse.set_visible() :

grab => False, visible => False => "virtual input" mode
grab => True, visible => False => "virtual input" mode

grab => False, visible => True => normal mode
grab => True, visible => True => normal mode

So as long as the mouse is not visible, it's considered "virtual
input" mode
I'm pretty sure this is a bug.
I hope someone will try this my code under Linux and tell me if it's
the same problem or not.

You cant get the whole sourcecode here:

By the way, Enigma (the only fullscreen SDL game I've tested under
Linux) has exactly the same problem.
