Test case:
1. mir_demo_server_shell
2. mir_demo_client_egltriangle
3. Press the power button to sleep
4. Press the power button again to wake up
Expected: Rendering continues on screen after wakeup
Observed:
ERROR: /home/dan/bzr/mir/dev/src/platform/graphics/android/real_hwc_wrapper.cpp(60): Throw in function virtual void mir::graphics::android::RealHwcWrapper::set(hwc_display_contents_1_t&) const

Update: I just found this is happening because unity-system-compositor is still running. If I freeze USC (kill -STOP) then the problem goes away. |
