(This is likely an upstream issue but raising here first to see if anyone else can confirm the bug)

AMD Radeon RX 570

Steps to reproduce:

1. set DPMS to very short timeout for testing purposes, eg:
$ xset s off dpms 10 10 10

2. open chromium and play any video (eg: YouTube)

3. close tab that played the video, but leave chromium running

4. note that DPMS screen blanking no longer works

Downgrade back to chromium-101.0.4951.64 and everything works again.
This task depends upon
