Watched these YouTube videos:
https://www.youtube.com/watch?v=b4rRtbsr_RM
https://www.youtube.com/watch?v=Yxk5zQNsANg

Actual results:

The first video was completely unwatchable (just artifacts all over), and the second video sometimes had some weird discoloration in four vertical bands.

Expected results:

Both videos should have played flawlessly.

The artifacts look similar to the ones shown in the following bugs:

https://bugzilla.mozilla.org/show_bug.cgi?id=1198366
https://bugzilla.mozilla.org/show_bug.cgi?id=1677344

My system is:

Operating System: Fedora Linux 36
KDE Plasma Version: 5.25.3
KDE Frameworks Version: 5.96.0
Qt Version: 5.15.3
Kernel Version: 5.18.11-200.fc36.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 32 × AMD Ryzen 9 5950X 16-Core Processor
Memory: 31,1 GiB of RAM
Graphics Processor: AMD Radeon RX 6600 XT

If I set media.hardware-video-decoding.enabled in about:config to false, then restart Firefox, the videos then play normally.
