GPU TDR with fullscreen quad

Sherief — Mon, 16 Nov 2020 05:47:37 GMT

System Used: (Manufacturer/Model): Razer Blade 15 Advanced
CPU SKU: (i3, i5, Pentium, Celeron, etc.) i7 9750H
GPU SKU: (HD4400, HD5100, etc.) UHD 630
Processor Line: (Y-Series, U-Series, etc.) i7
System BIOS Version: Razer 1.02
CMOS settings: Seriously now.
Graphics Driver Version: 26.20.100.7261
GOP/VBIOS Version: [Not sure how to check]
Operating System: Windows 10
OS Version: 1909 (Build 18363.1198)
API: D3D12
Occurs on non-Intel GPUs?: No

A simple application with 12 D3D calls (only one of which is a draw call) and one ECL per frame started throwing TDRs on the setup above. All it does is take a CPU-provided image and blit it to a texture resource then display it on a screen-aligned quad.

I kept simplifying shaders down to a passthrough VS and a constant color FS, removed the blit, removed texturing altogether, and simplified the root signature down to nothing, and issuing the draw call still causes a TDR.

I reverted to older builds that used to work and they now exhibit the same behavior, leading me to believe this was introduced sometime between May and November.

I can provide the binaries involved if required, preferably through a private channel.
