Summary: with fullscreen mode=driver killing client when on
another VT and returning to weston segvs
Severity: normal
Classification: Unclassified
OS: All
Reporter: rob at robster.org.uk
Hardware: Other
Status: NEW
Version: unspecified
Component: weston
Product: Wayland
Using gstreamer-vaapi hacked to use fullscreen mode 'driver' if you kill the
client whilst on another VT e.g X and then switch back to weston then it SEGVs.
Killing the client whilst remaining on the weston VT has no problem. Here is
