How about the very old Intel GPUs that are not capable of hardware overlay? Doesn't this force overlay support for those old GPUs as well?

Make sense. I thought it would do the same thing as https://source.chromium.org/chromium/chromium/src/+/main:gpu/config/gpu_driver_bug_list.json;drc=2553083e62303604676e81590ddcf14c1475e43d;l=3462.

Is this the same as bug id 346 above, since 10.0.26100.4061 < 32.0.101.6314 already?

These are two different things (OS vs driver), which means it requires two fixings (one is in Windows OS 10.0.26100.4061, another one is in Intel driver 32.0.101.6314) to make RGB10A2 overlay check API work.

Thanks. I missed that one is the OS and the other is the driver.

Change information

Commit message:

Enable RGB10A2 overlay support for HDR video playing on Intel

Two parts of the fixing have been done in Windows OS and Intel driver:
1. RGB capability report (including RGB10A2) issue inside Intel driver
2. Windows D3D API fails to deal with RGB pixel format

Both of the above have been landed and rolled out into public accordingly.
