Intel Arc driver issue on vulkan

[Omidv34]

Sorry if this is not the correct place to ask but I'm observing a weird issue on Intel Arc gpus that I"m pretty sure related to driver. The issue happens in form of a TDR (vulkan device lost) when sampling a specific image after writing to it in a previous pass. Now why the issue is weird. First of all there is no validation error/warning whatsoever (tried all the validation layers). Second, the same hlsl code and host setup (same barriers, execution order, etc.) work fine with our DX12 backend. Moreever this is an Intel Arc gpu only as we tested our game on different NVidia and AMD gpus and saw no similar issue. I also tried Intel GPA Tool but it only supports DX12 to capture frames so probably have to wait for a Vulkan release. But aside from that, is there anything we can try to better debug the TDR?

Thanks. I forgot to mention frame caputre with RenderDoc and PIX (for dx backend) doesn't show any critical error or visual issue. I also  used the captures to check the values read/written in the aforementioned passes but saw no unusual value.
