Gnome 46/Wayland + Firefox + YouTube stutterng

[logrusx]

Today I updated and noticed the update included Gnome 46. However now I observe stuttering in video playback in YouTube.

By chance in my YouTube feed there was a video about this Gnome feature that has been requested for so long and it turned out to be variable refresh rate, coming in exactly v46. By playing with the refresh I found out the stuttering was worse at the highest rate. I didn't try anything else other than the highest and the lowest, but what made me curious is why I have two 60.01Hz entries for my internal display. The external one has only one entry for 60.02Hz which is expected as it is 17 years old Eizo.

I also tested it with Xorg and on the dGPU which is Nvidia and it looked like on the dGPU the stuttering was significantly decreased but still noticeable, both under Wayland and Xorg and there were only two entries for my internal display - 60.01 and 165 Hz.

However I know my iGPU which is AMD Vega 10 or something (Ryzen 7 5800H) is perfectly capable of playing 1440p and the stuttering is noticeable on 1080p as well. I also don't want to use the dGPU as the stupid binary driver dims the display due to inactivity too soon, the GPU consumes power and spins fans harder and more often due to the higher thermal output.

Does anyone else experience this?
