It’s not the biggest issue I managed to fix, but it was definitely the hardest to figure out a fix for:
Whenever I would boot up any game on my Linux machine I would have microstutters ever so often, and it was frequent and lengthy enough to be very annoying, and thus started my 2 month long quest to figure out what was going wrong.
To cut a long story short, the compositor I was using had suddenly decided to do a breaking update and change the names of the backends they were using.
