            Bug ID: 99433
           Summary: Hardware accelerated windows freeze on animations
           Product: xorg
           Version: 7.7 (2012.06)
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Driver/Radeon
          Assignee: xorg-driver-ati at lists.x.org
          Reporter: bodqhrohro at gmail.com
        QA Contact: xorg-team at lists.x.org

After the reboot preceeded by several system upgrades I started getting X.Org
frozen on Compiz animations. The input is still processed during a freeze, even
mouse cursor can be moved and it changes according to underlying content but
the screen image is not repainted. After switching to tty1 and back the freeze
is temporarily gone. Firstly I thought this is a Compiz issue and posted
https://bugs.launchpad.net/debian/+source/xorg/+bug/1656328 but when I replaced
Compiz with Marco, freezing still affects hardware accelerated applications
such as browsers; now only their windows accidentally get frozen and this still
can be resolved by switching to tty1 and back.

Distribution: Debian Stretch (Testing).
xserver-xorg: 7.7+18
