It's not fixed at all in the latest Steam os update.
The micro stutters only show when in game mode. Switch into the KDE plasma desktop and see that there is no problem. I think the problem in game mode has something to do with the Wayland protocol/compositor. Desktop uses X11.
So for now, you have to play in desktop mode. You should also disable threads for much better emulation performance. I wrote a script that I run to enable/disable SMT. The performance is staggering when running 3 threads as opposed to the full 8, often allowing games to run at a full 60fps with no slowdown. A great example to test this is Mario Kart Wii.
