Ok, Thank you for suggestions Sergio, I also never used Apitrace. The black list seems to be a good thing even if it can't work for us as for the moment we have our homebrew 3D engine that directly call opengl. If you have tips to migrate our engine to Angle I will be interested because the last time I took a look I fell on build issues with glew and other dependencies we have that also includes opengl headers.
Angle seems the way we should take to improve compatibility of our application under Windows, we have few other issues that might be related to OpenGL. I hope that Vulkan will get a better support under Windows as it seems much more well defined. 2017-04-20 21:23 GMT+02:00 Sergio Martins <sergio.mart...@kdab.com>: > On 2017-04-20 20:04, Xavier Bigand wrote: > >> It is not necessary a bug from Nvidia, it can comes from bad >> parameters to functions like glDrawElements. >> > > Could be, but you'll have to prove it. > > I suggest: > - Create a minimal-testcase which reproduces the problem > - Run apitrace on it [1] (Never used it on Windows, but there are binaries > for it) > - Re-run the trace under apitrace, hopefully it crashes > - Check if your hypothesis is correct (bad glDrawElements) > - If it's an nvidia bug: Report to Nvidia, attach trace > - If it's an nvidia bug: Open a Qt bug report so the card can be > blacklisted > - If it's non an nvidia bug: Report a regular Qt bug so it can be fixed, > attach trace > > > > [1] - http://apitrace.github.io/#download > > Regards, > -- > Sérgio Martins | sergio.mart...@kdab.com | Senior Software Engineer > Klarälvdalens Datakonsult AB, a KDAB Group company > Tel: Sweden (HQ) +46-563-540090, USA +1-866-777-KDAB(5322) > KDAB - The Qt, C++ and OpenGL Experts > -- Xavier
