URGENT: OpenGL 2.1-based application crashes on Intel HD 3000

[NNeme1]

We are about to release a new application as Chrismas gift, expecting 20.000+ downloads by customers who are accustomed to receive top-quality products from our company.

This release is our first product based on Qt5, using the OpenGL-2.1-based QtQuick framework for graphics display (see http://qt-project.org/ http://qt-project.org/). The software has been extensively tested and runs stable on a wide range of machines with various graphics cards. We had occasional reports about Intel HD cards where even driver updates did not resolve problems. Now we have finally managed to reproduce and investigate one of those crashes in-house.

On a Windows7 machine with the Intel HD 3000, the application crashes on a segfault somewhere deep inside ig4icd64.dll. The crash originally occurred with the driver version 9.17.10.3347 (2014-01-29) installed. Updating to the latest version via the Intel Update Tool (15.28.22.64.3517 from 2014-04-10) did not fix the problem.

Please contact me so I can send you the binary and instructions to reproduce the issue.

Hi Norbert

Are you also seeing the issue on newer Intel Graphics such as HD 4000/4400/5000 etc?

Thanks

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:

https://bugreports.qt-project.org/browse/QTBUG-42240 [# QTBUG-42240] Crash when starting opengl application - 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.

Thanks

Robert
