How are RDNA 1 and 2 (AMD RX 5000 & 6000 series) cards on Linux nowadays? - SLRPNK

I read a few posts from a few years ago that they suffered from some sort of ring crash bug frequently. If you’re currently on either of those cards, how is the stability nowadays? Any hiccups or problems, or is it 100% in gaming now? Bonus question, does the Mesa driver allow you to access the VCN video encoder on the gpu?
