Oh, ok. That makes some sence. I had a similar issue with Fedora 41 as they didn’t update to a newer version of FFMPEG that fixed some conflicts/issues. I had to download a different video player that shipped with it’s own ffmpeg packaged. Can’t remember the name, but try seeing what’s in the software store. You might be affected by a similar problem.

That is even stranger. My RX6600 has zero issues with 4k 10bit content. Do you watch via browser or ripped dvds?

You could try one of the “gaming” focused distros like Cachy or Bazzite. They do their own tweaks to squeeze more performance out of you hardware. Sadly, many game won’t reach the performance level of Windows, but you can get pretty close, like 85-90% close (depends highly on the game in question, no guarantees).

I second OnlyOffice. I am not a power user of Word, but neither a novice. Things haven’t broken yet and I’ve been editing .docx files for over a year now.
