There are a number of issues with this driver on the Windows on ARM platform including green frames and BSOD crashes. The green frames issues are expected to be fixed in the updated driver.

This driver version is known to have busg which cause the output of green
frames from the decoder, and to cause BSODs.

Reproduced on Windows 10 on ARM platform (Laptop Lenovo Yoga) on the latest Beta 67.0b17.

Chris, is that something we could uplift to 67?

Bug 1548410 - Disable DXVA on Qualcomm WoA drivers. r?mattwoodrow

Beta/Release Uplift Approval Request

  • User impact if declined: BSODs while playing video
  • Is this code covered by automated tests?: Yes
  • Has the fix been verified in Nightly?: Yes
  • Needs manual test from QE?: No
  • If yes, steps to reproduce:
  • List of other uplifts needed: None
  • Risk to taking this patch: Low
  • Why is the change risky/not risky? (and alternatives if risky): This blacklists the driver for hardware video decoding on a specific Windows on ARM64 device; we'll fallback to software decoding, which will not be as performant, but will be more stable.
  • String changes made/needed: None

Given the regressions we should probably back this out from beta and m-c.

Or... Hmm. I guess those regressions aren't as bad as the BSOD that this update is trying to fix. Chris, what do you think?

There is supposed to be a new driver coming to these devices soon, and once that's released the regressions from this should be fixed. Probably best to await the new driver and let this ship.
