Laggy windows on rtx 4060 + wayland

[mandarancio]

Moving windows and resizing them makes the system lag, i also expirience some input lag while using vscode (that runs on electron).

I had this problem for months and any update could solve this.

Operating System: Fedora Linux 41
KDE Plasma Version: 6.3.0
KDE Frameworks Version: 6.11.0
Qt Version: 6.8.2
Kernel Version: 6.12.13-200.fc41.x86_64 (64-bit)
GPU: RTX 4060
NVidia drivers: proprietary v. 565.77

Grub is set up correctly to load nvidia drivers: /etc/default/grub: GRUB_CMDLINE_LINUX="rhgb quiet rd.driver.blacklist=nouveau modprobe.blacklist=nouveau nvidia-drm.modeset=1 nvidia-drm.fbdev=1 amdgpu.dcdebugmask=0x400"

Hi! If you’re using the closed-source kernel drivers, have you also tried disabling the GSP firmware by adding nvidia.NVreg_EnableGpuFirmware=0 as a parameter to your Linux kernel command line?

That’s the one step I found necessary on my newest device - with a new enough graphics card to have the GSP to begin with - to remove pretty much all the weird stuttering and lagginess from the Plasma desktop when using a recently-released Nvidia card. In my opinion, it’s worth trying if you’re getting a weirdly “janky” experience.

I don’t disable GSP firmware anymore, and I no longer experience the desktop jankiness.

i have added the string and then i have run grub2-mkconfig -o /boot/grub2/grub.cfg. but the problem is still there.

So the problem seems to be touchegg, according to journalctl:

feb 17 14:32:34 ErPicci.lan touchegg[3055]: Error connecting to Touchégg daemon: Could not connect: Connection refused
feb 17 14:32:34 ErPicci.lan touchegg[3055]: Reconnecting in 5 seconds...

so, randomly, i run: systemctl enable --now touchegg, and now performance are a little bit better. some times there is still lag while resinzing and moving windows but at this point i think it’s a driver problem.

Or touchegg causing other issues.
You could systemctl disable --now touchegg for a minute to check.

i get better performance with touchegg disabled, and since i don’t need gestures on my desktop i’ve removed it. However, i still experience lag when i open certain apps: like spotify and vscode that are based on electron, or firefox, and resizing those sometimes makes my cursor lag.

I have a Ryzen 7700x cpu with 32gb ram, so, i guess it’s not a performance problem.

In case it’s relevant to your situation as well, maybe try ramping up your minimum GPU clock?

KDE Plasma | Wayland + Nvidia | Low fps, Stutters

For what it’s worth, here’s my working theory - based on 90% speculation With all the focus on high-end performance, maybe some of these modern big rig desktop graphics cards - built and benchmarked for cranking out 9,000 FPS for hours in a row on Call of Duty - might not naturally perform as well at the basic desktop computing demands of “chill for 30 minutes, boost up quickly to render this menu, then go back to chilling.” Perhaps they need more assistance from the software and…

My understanding is that generally, the graphical effects on your desktop - unless it’s using software rendering - are GPU-bound rather than CPU-bound. If that’s the case, then even a really souped-up CPU might not avoid issues caused by inefficiencies in the GPU’s functioning.
