Minecraft after switching from fullscreen

When switching between fullscreen and window in the game Minecraft, or when
pressing F12 to render the scene in Blender, I'm getting a a corrupt screen.

Sometimes it looks like it contains traces of a previously running gl
application, so maybe some buffer or something isn't cleared properly?

This isn't a new bug (seems to be present at least as far back as 7.9) or a
very important one, but would be nice if it could be fixed.

I should also mention that this problem doesn't appear with llvmpipe, so I
guess it's specific to r300g.

I'm having exactly the same problem on r600g, so maybe this bug belongs to
xf86-video-ati?

Thanks for reminding me to re-test this.

So with r600g I can no longer reproduce this with Minecraft or Blender, but
both are moving targets and no longer the same version I was testing with so
I'm not sure if it was fixed in the driver or not.

If no one else has these issues I think we can consider this problem solved.
