Hello,
I am part of a team working on an application that uses OpenGL for some some things. However, it seems that on systems that make use of an (integrated) ARC GPU, and using the latest Intel graphics drivers (latest tested is 32.0.101.6559, older drivers have also been tested), our application would freeze and crash very often soon after starting. We did only test with integrated ARC GPUs, no dedicated ARC GPUs. On non-ARC based GPUs we don't see the freeze/crash issue. The laptop CPUs we have seen the problem with are: Ultra 5 135U and Ultra 7 155U. Both have a "Arc Xe-LPG 64EU".
If we use a Mesa driver (18.x) on the ARC-based laptops instead to do all the OpenGL processing on the CPU, then our application would not crash on the ARC-based systems. This, along with the fact that we don't see issues with non-ARC-based laptops, leads us to believe that there might be a bug in the Intel graphics driver for ARC and OpenGL.
Additionally, while the stack traces of specific crashes can differ, they always relate to an OpenGL call. The exception code is always "C0000005 ACCESS_VIOLATION" and the faulty module is always "igxelpgicd64.dll".
A similar reported issue is this: Re: Thinkpad T14 gen5 intel arc graphic BGFX OpenGL TDR - Intel Community
Kind regards,
