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.

Weird stuttering on fresh Fedora 42 GNOME install (www.youtube.com)

EDIT: This has worked, thanks for help: LD_PRELOAD="" VK_LOADER_LAYERS_ENABLE=VK_LAYER_MANGOHUD_overlay_x86_64 %command% --skip-launcher --vulkan

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?

Is this launching games through Steam? I had a similar issue launching games through Steam using gamescope and had to set some launch options. Unfortunately I am at work and can't remember what those launch options are but when I get back home I will add them.

Edit launch options: LD_PRELOAD="" gamescope -ef -W 3840 -H 2160 -r 144 --hdr-enabled --adaptive-sync --mangoapp -- gamemoderun %command%

As others have mentioned I think it was the "LD_PRELOAD=" that actually fixed the issue
