Has anyone of you experienced application crashes when running a Qt application that uses OpenGL over remote desktop on Windows 10?
We ran into a reproducible crash that is restricted to a certain scenario. The crash occurs in QGlContextPrivate::syncGlState() when trying to call glDisableVertexAttribArray(). It seems the function pointer is not available. However, there are some other factors involved: - the crash happens *always *when the application is run over a remote desktop connection, but *never *if run on the same machine directly - the crash happens *always *with the application linked to Qt 5.12.4 (or .5), but *never *when linked to Qt 5.6.2 - the crash is restricted to two machines (out of a larger pool), one with a GTX 560, the other with a GTX 745 graphics card - all machines we used in testing are running Windows 10 Enterprise 64bit, with different versions (1803 to 1903, but all updates installed) - installing the latest available Nvidia drivers does not solve the issue We would be happy to hear of any comparable issue, ideally together with a solution for it... :-) Cheers, Rainer -- Software Engineer | Trimble Imaging Division Rotebühlstraße 81 | 70178 Stuttgart | Germany Office +49 711 22881 0 | Fax +49 711 22881 11 http://www.trimble.com/imaging/ | http://www.inpho.de/ Trimble Germany GmbH, Am Prime Parc 11, 65479 Raunheim Eingetragen beim Amtsgericht Darmstadt unter HRB 83893, Geschäftsführer: Dr. Frank Heimberg, Jürgen Kesper
