Stuttering and lag in some apps in Zorin 17.2 Pro

Hi, i'm using Zorin 17.2 pro and i noticed big stuttering in certain apps like discord and libreoffice. Is very noticeable compared to other apps (specially because i'm using a 144hz screen).
I had to install Goofcord as alternative to discord.

My pc specs:

CPU: amd ryzen 9 7900
GPU: nvidia rtx 3090
RAM: 32 gb ddr5
Screen: 4k 144hz (scaled at 200%)
GPU Drivers: NVIDIA-SMI 550.107.02 Driver Version: 550.107.02 CUDA Version: 12.4
OS: Zorin 17.2 Pro (packages updated)
Everything works fine including game engines, is just software like discord, libreoffice (i had the same problem some time ago with brave till recent app update)

Are you using Wayland or Xorg? What you've just described sounds EXACTLY like the problem I have with Nividia on Wayland. I've used Wayland on other distributions that push for newer versions and not had this problem, but I believe other users have mentioned that until Zorin moves to a newer version of GNOME, the only fix here is using Xorg.

right now x11.
wayland is just unusable with nvidia and have different problems like non stop stutter and sometimes buffer problems because previous frames are overlapped over the current one.

Huh. I'll have to defer to someone else then, sorry. I've only experienced this with Wayland, myself.

Nvidia driver it self is unstable, be aware of the 560 one if it comes to zorin

Welcome to the Forum!

Are the problematic Apps Flatpak's, Snap's or .deb Versions?

with libre office the problem was the default one which comes with zorin os and discord is the one which comes from the software store (from flathub repository), so i assume it came as a flatpack.
