(Get the code!)
My application reliably produces a GPU hang using the attached apitrace log.
A few seconds before the screen flickers / GPU resets, the X server does not
seem to receive/process updates (i.e. mouse movements). Then the screen
flickers once and after that mouse movements are processed as normal. I've
made multiple apitraces, and sometimes this appears to happen twice per run,
other times it just occurs once... might be a timing thing with how quickly I
can close the window after the first hang.
The hang+reset is reproducible with the attached apitrace log.
