** Description changed:
confirmed to happen in latest image with usc0.3 and previous images with
usc0.2
steps
1) flash ubuntu-touch/rc-proposed/ubuntu-pd
2) connect bt mouse and see unity8 go into windowed mode
3) move mouse about screen while at the same time connect slimport hdmi cable
ui will then freeze but seems content, let it sit for 30 min no reboot or
restart, no crash files, power button does not do anything.
It's also possible to have the slimport already connected - move mouse around
disconnect, the ui will freeze altho in this case unity8 always seems to
restart.
There are no usc crash files.
+
+ The problem is a dead lock on the Display/DisplaySyncGroup mutexes
+ between CompositingFunctor->SystemWindowManager->GraphicsDisplayLayout
+ and DisplayInputRegion.
