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.
