I was just wondering, the mouse drawing from the timer works like this
in principle:
acquire_bitmap
screen->clip = TRUE
/* switch occurs here */
draw
restore screen->clip
release_bitmap
But now, what if the timer thread is switched out just before draw, as
indicated above, and the main thread modifies the clipping of the
screen. Wouldn't this cause a crash? Am I overlooking something?
If not, this would be bad, maybe even explain some strange crashes
(besides the one Julien got in my modified exkeys). But I feel I'm
missing something obvious..
