Uff. I suspect it's related to this snippet from the ChangeLog[0]:
* The driver now takes measures to prevent other DRM master processes
(potentially from other local users) from accessing buffers created by
this driver while switched away to a different VT. Other DRM master
processes should only be able to access a single buffer anymore, which
contains only all-black pixels.
Are you willing to report this bug upstream? See here for information:
https://freedesktop.org/wiki/Software/xorg/
We should probably revert this on 'master' meanwhile. Unfortunately I
don't have ATI hardware to test with, so it would be good if someone
else could try to reproduce this problem.
