Hi, so I've been using Fedora 41 GNOME since release with no issues at all and I've decided to do a new fresh install of Fedora 42 yesterday.

Everything seemed to run well but I've encountered this issue in games that after around 30min I get this weird stutter. Until then everything runs smoothly.

As you can see in the video the stutter only occurs during mouse movement or during camera movement with keyboard. Once the camera moves on it's own and just tracks the character the frametimes are perfectly flat so it does not seem like the fault is on the game but somethings off with the system compositor?

This happens with or without VSync, I've tried with and without VRR, I've tried chaning game settings and also different Proton versions... only thing that helps is to restart the game but then I'll have to do it once again in about 30min.

My suspicion is on the new triple buffering in new GNOME 48 but I have no idea how to turn it off to test.

Any suggestions?

I don't use Fedora, but do you know if your kernel or GPU drivers have been updated to a newer version? If so, there could be some kind of bug causing it, and you could try downgrading your packages. I would also check to make sure the refresh rate on your monitor matches your OS. The Steam logs would also be a good place to start, if you haven't checked them yet.

I was on 6.13.x kernel, now 6.14.x and yes, also went forn MESA 24.x.x to 25.x.x which is default for Fedora 42 now. Refresh rate is fine. Not sure what I should be looking for in the Steam logs. Game is not crashing and otherwise seems to be running fine unless I use any kind of input when this starts to happen.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
