            Bug ID: 97815
           Summary: Unresponsive weston with flickering image after
                    hibernation
           Product: Wayland
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: enhancement
          Priority: medium
         Component: weston
          Assignee: wayland-bugs at lists.freedesktop.org
          Reporter: serega.belarus at gmail.com

Distribution: Arch Linux
Hardware: AMD E-450 APU with Radeon 6320 HD
Kernel: 4.7.2
Weston: 1.11.0

Description: After resuming from hibernation (systemctl hibernate), weston's
image flickers but display mouse cursor or totally garbaged with random noise.

Quitck-Fix: Switch to another VT, then suspend and resume machine (systemctl
suspend, not systemctl hibernate this time), switch back to weston's VT.

There is similar behaviour mentioned in another weston's issue:
https://bugs.freedesktop.org/show_bug.cgi?id=95086#c1

Steps to reproduce:
- Launch weston (dbus-launch --exit-with-session=weston)
- Run hibernation (systemctl hibernate)
- Resume from hibernation
- You see weston session's image, or just random noise, that flickers when
mouse is moved. It depends on boot, that you can see normal cursor point, but
no more.
Looks like clicking upon launcher icons, runs those applications, but the
picture
is corrupted.

Here you can see logs from weston, as well as dmesg and systemd messages
related to suspend and hibenation, the weston config added too:
