Green screen at empty spaces when play HDR videos

[poonnawit]

I'm a MPC-HC user. It happens only when play every HDR videos. If I play 16:9 video and toggle to Fullscreen, there still no green because my monitor has 16:9 (1920x1080) same as the video. But the green screen will appear at the empty space of the player (It should be black) when the video not a 16:9. Also, in window mode when try to resize window that video does not fill the player space.

Default size after open video

When resize window width

non-16:9 Video with full screen

Video still play smoothly and no problem with video. But the screen has some over-brightness sometimes and become normal brightness when toggle full screen a few times. (Only in HDR videos)

Windows 10 22H2 CPU: Intel Core i5-4570 GPU: AMD Radeon RX 6600 XT (22.11.2) Monitor: BenQ EX2510S (1920x1080) (HDR10 Support)

Press Ctrl+J to show the renderer debug overlay. Make a screenshot of that as well.

Test if changing the hardware decoder setting in LAV Video Decoder has any effect on this problem.

Test in MPC-BE. Test without HW decoding. Show screen with statistics(Ctrl+J).

I think I have found the answer. When try to uncheck "Use for resizing" the green screen have disappeared. Maybe scaling is the problem. I guess.

Look's like driver issue.

I tried switch to use madVR and there is no green screen. But when I resize the window. It's look like a bit more delay than MPC VR. Windows only auto switch to HDR mode when full screen. Maybe this try has some clue.

madVR use Direct3D9 internal and Direct3D11 only for output. As i said - it's some driver issue.

Check test build. But I warn you - sometimes it may not produce a picture on HDR at all, in which case we simply reopen the file (maybe even several times). MpcVideoRenderer-0.6.4.1966_git2023.01.04-e90179d.zip

No changes. And still produce pictures as well. No need to reopen. I have reported this issue to AMD. If next drivers have arrived, I will update the issue on there. Thank you.

Update: The issue has been fixed on Adrenalin 23.2.1 (WHQL) driver. No more green space.
