Intermittent Display Glitching/Rendering/UI Distortion

[ryanfinger 6]

Weird issue so bear with me...

 

I have Emby Server and Theater on the same machine.

 

2-3 times a week, usually while watching something 1.5-2 hours in length I experience a situation that requires a full restart of the Windows 10 machine to recover.

It first starts with MPV.  The video begins to glitch and fade in and out.  It's not a bitrate or bandwidth issue, it feels like some sort of bug or glitch.  Exiting out of the video and going back to the Emby UI has the same display glitches and rendering.  At this point I restart the machine.  Once it comes back up and Emby is launched I can start the video from where I left off.

 

Since I don't know what the issue happens it's difficult to setup to capture logs.  Here is what I have done so far...

 

I'm the latest version of Emby Theater and Emby Server (v4.4.2 and v3.0.11)

I've played around within Emby Threater with enabling and disabling hardware acceleration.  No changes.

I've updated my Nividia drivers to the latest greatest, no change

This problem seems to happen over prolonged viewing.  I don't experience this watching typical TV shows or LiveTV.  100% of the time I am watching a Movie.

The movies that I watch are various qualities, bitrates and encoding.  The majority of what I watch are 720p/1080.  None of the movies were 4k.  Last night I was watching an 80s movie that was SD.

No transcoding is going on.  All movies are DirectPlay.

 

If you need logs LMK how best to accomplish that given I don't know when the issue will happen and I cannot reproduce on command.

 

Thanks,

Ryan

It's not a bitrate or bandwidth issue, i

But it could be though, right? It could also be a corrupt file, graphics driver problem, lots of potential causes unfortunately.

If it was bitrate it would not cause the Emby Theater UI to also have the same problem. If it was a corrupt file restarting would not resolve the problem. Also, it has happened on many different files.

What do you mean Emby Theater UI?

[ryanfinger 6]

Emby Theater User Interface. Main screen with my media, continue watching, next up, etc.

[Luke 42078]

What exactly is the problem with the user interface? I don't quite understand sorry.

[ryanfinger 6]

Can you please reread my original post Luke and tell me specifically what additional questions you have as opposed to me restarting the problem again. I was very detailed in my initial write up.

[Luke 42078]

It seems like everything you've described is about video playback so i wasn't clear about the problem in the UI.

I will try and see if I can do a video capture on my phone and give you the link so you can see for yourself.

Great, thanks !

Problem happened again last night watching a series as opposed to a movie.  Same behavior.  I took a video.  The video makes it look about 1/2 as bad as it actually is.

You can see the glitch and distortions throughout the clip but its really noticeable about 19-20 seconds in.

 

At this point if I restart the PC and start watch the SAME file at the SAME point there is no glitch or distortion and it plays without issue.  Restarting the PC is the only fix.  If I stop the video and simply restart it the glitching continues.

Great, thanks !

Did u look at the video?

[ryanfinger 6]

@@Luke Did you take a look? Thx.

I was able to fine the root cause of this.  Windows suggested that I set the scaling to 300% since I'm running in 4k.  Adjusting the scaling to 200% while the issue was occurring caused the problem resolve.

That's interesting. Thanks for the feedback !
