            Bug ID: 69514
          Assignee: dri-devel at lists.freedesktop.org
           Summary: R770 (Radeon 4850) screen/buffer corruption when
                    waking up from sleep mode
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: peterasplund at gentoo.se
          Hardware: Other
            Status: NEW
           Version: XOrg CVS
         Component: DRM/Radeon
           Product: DRI

If I put my computer in sleep/hibernate (doesn't seem to matter which one) the
screen gets corrupted with colors everywhere. It does update, and things jump
around when I try to press buttons, bring out menus, etc. It's like the drawing
buffer is all jumbled up and it's reading/writing from/to the wrong place.

When something is updated, it's like I can see the picture/pixmap/icon for a
fraction of a second, but then it's corrupted again.
If I move the mouse continuously over a menu, to update the highlighting of it,
I can see at least where I am on the screen. But the fonts are complete
garbage, and it's unreadable. Perhaps I can photograph the screen if it's
needed. I haven't tried taking a screenshot.

I'm using Gentoo, 3.11 gentoo-kernel, with Systemd and Gnome 3.8.

The TTY:s are not corrupted, so I'm able to switch to a TTY without problems.
