Known Driver Issues

This page lists known issues with drivers that are not, or cannot, be worked around by wgpu.

Issues are categorised by GPU vendor and backend. Where details such as "driver version" are recorded, they are not intended to be exhaustive: these are just the values where the issue has been observed. Just because your combination is not explicitly listed does not mean you aren't susceptible to the same issue.

Intel / Vulkan

• Integrated GPU not visible to programs named cube

  Property	Values observed
  Operating System	Windows 10 64-bit
  Driver OEM	Intel, Microsoft
  Driver Version	27.20.100.8935

  In a dual-GPU system, the driver for the Intel GPU will hide itself from programs named cube.

  The issue can be worked around by disabling the discrete GPU or by renaming the program to something other than cube.

Intel / DirectX 12

• Offset after resizing window

  

  https://github.com/gfx-rs/wgpu-rs/issues/647

  Property	Values observed
  Operating System	Windows 10 64-bit
  Driver OEM	Microsoft
  Driver Version	26.20.100.7639

  This issue affects programs running on any GPU if the Intel GPU is being used by the compositor. This would typically be the case in dual-GPU systems.

  It can be worked around by replacing the Microsoft OEM driver with the generic Intel driver.

• CreatePlacedResource TDRs

  https://github.com/gfx-rs/wgpu/issues/1319

  Property	Values observed
  Operating System	Windows 10 64-bit, build 19042
  GPU	HD Graphics 4600
  Driver Version	20.19.15.5171

  Reported in https://github.com/IGCIT/Intel-GPU-Community-Issue-Tracker-IGCIT/issues/44

Intel / DX11

• Buffer write not synchronized with draw

  https://github.com/gfx-rs/wgpu/issues/1060

  Property	Values observed
  Operating System	Windows

  Buffer upload isn't being properly synchronized with the draw call that is using it. This is entirely on the driver to get right, there is no way to do manual sync.

Intel / All

• Cannot combine MSAA with Srgb resolve

  https://github.com/gfx-rs/wgpu/issues/725

  Property	Values observed
  Operating System	Linux

  Attempting to do MSAA resolve at the same time as Srgb resolve will cause MSAA to not work and the clear color to not be properly converted into Srgb.

Nvidia / Vulkan

• Hang/panic/device loss after specific render sequence

  https://github.com/gfx-rs/wgpu/issues/983

  Property	Values observed
  Operating System	Windows 10 64-bit
  GPU	Geforce RTX 2080 Ti
  Driver Name	GeForce Game Ready Driver
  Driver Version	456.38, 457.09, 457.30

  Does not occur on driver version 452.06.

  After submitting a frame to wgpu, Vulkan seems to become unstable and this manifests itself in a few ways.

WARP / D3D12

• CPU descriptors are used after CopyDescriptors

  https://github.com/gfx-rs/wgpu/issues/1002

  Property	Values observed.
  Operating System	Windows 10 64-bit

AMD / D3D12

• Updating partial texture data doesn't show up

  https://github.com/gfx-rs/wgpu/issues/1306

  Property	Values observed
  Operating System	Windows 10 64-bit
  GPU	Ryzen 3500U
  Driver Name	?
  Driver Version	?

  When a texture only gets partially updated, sampling from it returns zeroes.

  Issue has been reported directly to AMD.
