weston configuration file
Recording on multihead display configuration with weston-drm is unstable and
unpredictable...
On my sandybridge ultrabook with an LVDS+VGA multihead setup I have the LVDS
transform set to 90 degrees and VGA at default settings. When running
Weston-drm in this configuration, an attempt to record via <Super>+r more than
once in the same Weston-drm session causes Weston to lock-up or crash. Also,
during the first recording instance, moving the mouse over the
weston-desktop-shell toolbar on the VGA output results in garbled/corrupted
rendering.
See attachments.
Steps
------
Using the attached weston.ini configuration file and a LVDS+VGA display
setup...
1. Launch weston-drm: weston --backend=drm-backend.so
2. Start recording with <Super>+r
3. Move mouse over the desktop toolbar on the VGA display.
Issue: toolbar rendering becomes garbled/corrupted
4. Stop recording with <Super>+r
Issue: weston logs "stopping recorder, total file size 1M, 0 frames"
Issue: desktop rendering on VGA remains corrupted in some cases.
5. Start recording with <Super>+r
Issue: weston will either crash at this point or lock-up
