Public bug reported:
This issue has been around for a long time, at least since version 20.10
and IIRC also with 20.04 HWE updates.
I bought this Lenovo M73 Tiny for HTPC purposes, but due to these video
playback issues I am now forced to run it with Windows. At first it used
to work well, but has regressed with later Ubuntu or Linux releases.
1. Display refresh rate at 50 or 60 Hz
2. Play 50 or 60 fps video content with a browser: YouTube or sports broadcasts
from VOD services
--> Video playback stutters constantly, making it unpleasant to watch,
especially for sports.
100% repro on recent Ubuntu releases and also on Ubuntu-based PopOS.
