Comment 24 for bug 1318584

Thanks for testing. Technically the PPA tested was not the most up-to-date (if you read the instructions on the front page of that PPA, it points to the landing silo PPA that has newer packaging), but it should be good enough for this testing.

I still couldn't reproduce the problem for some reason on my setup (intel sandy bridge, laptop screen + external monitor) with either Qt 5.2 or 5.3 on utopic, but the fact that it also seems to happen on Qt 5.3 indicates it's not something that's fixed upstream.

The best way forward would be to file a Qt upstream bug report at https://bugreports.qt-project.org/ with a minimal test scenario. For example, if it's any Qt app, just qmlscene test.qml or such would be enough for the app part, and then describing how the actual crash happens and maybe trying to get a backtrace out of it.
