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?

Had the exact same stuttering on Arch Linux with BG3 - only when moving the mouse/camera after an hour or so of gameplay. Resolved it completely when I disabled the new Steam background recording feature and Steam overlay (on BG3 only). Not sure if it was just one of those things or both, but it hasn't happened since turning them off. Might be worth a try for you too~

Edit: Oh, also I have these launch options, I think the LD_PRELOAD="" might have been related to this issue too~

LD_PRELOAD="" VK_LOADER_LAYERS_ENABLE=VK_LAYER_MANGOHUD_overlay_x86_64 %command% --skip-launcher --vulkan

Seems like that has worked, thanks a lot!

I already have overlay and game recording disabled. I'll give those launch options a go, will let you know if it helped. Thanks.

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.
