Public bug reported:
This occurs with the development version of Mir running on 18.04LTS (not
seen on later series). (This version of Mir can be installed from ppa
:mir-team/dev).
1. Start multiscreen Mir-on-X: miral-app -demo-server --x11-output
640x480:800x600.
2. Position windows side-by-side to make it easy to move cursor across windows.
3. Drag the terminal window back and forth between windows.
Expect: everything works smoothly.
Actual: Eventually (can take 30sec) a core dump.
It looks like internal mesa state is inconsistent as src_mt is assigned with
intelImage->mt and not changed in ntel_miptree_copy_teximage() but...

Bug description:
This occurs with the development version of Mir running on 18.04LTS
(not seen on later series). (This version of Mir can be installed from
ppa:mir-team/dev).
1. Start multiscreen Mir-on-X: miral-app -demo-server --x11-output
640x480:800x600.
2. Position windows side-by-side to make it easy to move cursor across
windows.
3. Drag the terminal window back and forth between windows.
Expect: everything works smoothly.
Actual: Eventually (can take 30sec) a core dump.
It looks like internal mesa state is inconsistent as src_mt is assigned with
intelImage->mt and not changed in ntel_miptree_copy_teximage() but...
