Two (minor) issues I have right now in Linux (stuff I need to research more on how to mitigate, at least the first one):
RX 6800 with LG 27GL850: In Windows AMD patched like a 1-2 years ago the drivers to use 5W-10W while on desktop. On Linux it still uses 32W and the only workaround is to reduce refresh rate from 144Hz to 120Hz.
Audio: When switching between different audio devices (“Line out” and “S/PDIF” some apps do not handle the switch instantly like in Windows. So for example if I’m playing a song in Spotify and I want to S/PDIF (which is connected to some studio monitors in the living room in my case) I need to close spotify and open again. In Windows you can switch without interrupting the song. Same happens while gaming. (Restarting a game is a PITA). I also use S/PDIF with my wired headphones that I use for gaming.
