Because of this bug https://bugs.launchpad.net/mir/+bug/1238695 Ubuntu Touch on the Google Nexus 7 (grouper), Touch randomly freezes, and flickers.
It is bad enough that I cannot do anything except restart the device.
I was just wondering how to workaround this, can I switch back to the "surfaceflinger" that Touch previously used - as this was working nicely on previous versions?
