I just checked vivaldi://gpu and it's throwing out this :
[9620:2752:0711/161927:ERROR:gpu_video_decode_accelerator.cc(362)] : HW video decode not available for profile 12
As for what graphics system I'm using what do you mean by that and how do I find it?
Edit: OK so I have a dual monitor setup and I just tried youtube on my second monitor (in a separate window) and it worked. I then tried youtube back on the first and it didn't. After moving the second window onto the first monitor youtube seems to be working again huh. Nope not working again.
