Frames dropped while streaming Netflix 

 

The user Cornugon perfectly describe the issue I still have. Did ray_m come to a result?

I am running latest Windows 2004 Build 19041.388 and AMD 20.4.2. But any previous Windows version and AMD driver version have the same issue.

 

The issue is also happening with other videoplayers (Netflix is just famous, so thats why is mostly is mentioned in first place).

As soon the videoplayer is in fullscreen, the video drop frames, when Overlay/GUI Elements like the navigation bar or subtitles gets dispalyed or vanish.

 

In fullscreen, the video is only smooth when there are no elements displayed the whole time, or when "something is displayed the whole time".

 

For example the Netflix Windows 10 App:

 

The Video is in fullscreen, Navigation bar is displayed whole time and Subtitles start to appear -> not choppy

You display Videoinformations the whole time (Ctrl+Shift+Alt+D) and Subtitles starts -> not choppy

The Netflix App is in window mode and subtitles display -> not choppy

Only when video is in fullscreen and no navigation bar and subtitles appear -> choppy when subtitles appear and disappear

 

I have uploaded two videos to show. I am showing with MPC-HC, because it shows best when I rapidly display navigation bar with the mouse. The other half of the first video shows the Subtitles issue with Netflix.

 

On the second video I show how the issue is only in fullscreen mode, but not in window mode.

I have found only one workaround:

 

Setting compatibility mode of MPC-HC to Windows Vista fix the issue. Setting to Windows 7 or 8 does not. I have no idea why.

 

Another workaround could be to fake somehow invisible Overlay, like an invisible navigation bar or that the program is whole time in "window" mode (but it's actually fullscreen). Any tip would be great here.

 

The issue is even on the test video of the Windows 10 video test when you go to Settings -> Apps -> Video -> start the video, set to fullscreen and wait until navigation bar gets vanish -> it shortly will stutter.

 

I have this issue only on a system with AMD GPU. On my systems with Intel GPU or NVIDIA, it's always fine in fullscreen, no frame drops.
