Are you also seeing the issue on newer Intel Graphics such as HD 4000/4400/5000 etc?
Still looking for more machines in-house to try to reproduce this issue.
So far, I received a report on a machine with Intel HD 4000 running Win 8.1, which did *not* show any problem.
Turns out, a very similar looking crash has recently been reported to the Qt bug tracker:
... along with some repro code.
Based on how the crash behaves in debugging, I still believe that this is actually a driver issue. Perhaps the Intel support could cooperate with Digia/Qt to resolve this?
Managed to reproduce an identical-looking crash on a MiniMac with Intel HD 3000 running Windows7.
One other machine (MacBook Pro 13, non-retina) with Intel HD 3000 GT2+ on Windows did *not* show the problem.
Also machines with Intel HD 4600 and other have so far never displayed this kind of crash.
Thanks for the update. Currently, only issues found with HD2500/4000 (Ivybridge) and newer are being investigated. If you are able to reproduce the issue on Ivybridge or later please post an update to this thread.
