x265 videos with external subtitles causes brightness flickering

[Riki_Guitarist 0]

Hi. I'm watching videos on the Emby Library using Google Chrome on a Asus Zephyrus laptop. In x265 videos, the videos seem washed out. But when I enable external subtitles, or move my mouse over the video window to show the UI overlay, it temporarily makes the video look naturally saturated again. It also flickers to looking washed out each time new lines of subtitles appear.

Here's a video I recorded of it happening (audio intentionally muted):  https://imgur.com/a/gbCuLWa

I've also tried attaching the files to this post.

This doesn't happen when I play the exact same video on my desktop PC using the Emby Library in Google Chrome. I also don't get this issue when playing the same video/video type on my Android phone.

My video drivers are up to date, I've tried fiddling around with HDR mapping, software/hardware/off transcoding, etc. inside Emby. Nothing fixes it.

Videos with internal subtitles and x264 videos don't have this issue on my laptop.

I've tried searching online, and these are the exact problems I'm having. Although they're not for Emby:

 

 

 

I've tried some of the solutions for these posts, and they don't work. Any help would be appreciated.

Hi, given that we're direct playing, I don't think we can do very much about this. It is most likely an issue in the browser video player.

You could check the browser settings to see if hardware acceleration and try toggling that on or off (understanding that changing it might cause other side effects).

Hi,

For the record, I had a similar problem on a MacBook Pro using Safari.

I think that enabling a colored background instead of the default transparent one resolved my issue...
