[SOLVED] Weird video artifacts at 144 Hz with NVIDIA open driver
Hi,
I have an issue where setting my main display to 144 Hz causes weird graphical artifacts on the screen.
When I lower the refresh rate to 100 Hz, the artifacts disappear completely.
What I have tried so far:
Reinstalled the NVIDIA drivers
Fully updated the system and rebooted multiple times
Followed the steps from this post:
https://bbs.archlinux.org/viewtopic.php?id=284391
Tested different DP ports
Disabled and re‑enabled hardware acceleration in the browser and media players
My setup:
Kernel: 7.0.10-zen1-1-zen
GPU: NVIDIA GeForce RTX 2070 SUPER
Desktop environment: KDE Plasma 6.6.5
Session: Wayland (KWin)
Driver: nvidia-open-dkms 610.43.02-2
Monitors:
Main: Ultrawide 3440x1400 144 Hz (artifacts at 144 Hz, OK at 100 Hz)
Secondary: FullHD 1920x1080 75 Hz (no artifacts)

Re: [SOLVED] Weird video artifacts at 144 Hz with NVIDIA open driver
for OUT in /sys/class/drm/card*; do echo $OUT; edid-decode $OUT/edid; echo "================="; doneYou'll need https://archlinux.org/packages/extra/x86_64/v4l-utils/
Also
kscreen-doctor
qdbus6 org.kde.KWin /KWin supportInformationCan you quantify "weird" (ie. link a picture/video or so)?
Do you get the same w/ plasma/X11?
https://en.wikipedia.org/wiki/DisplayPo … esolutions
You'd sit between HBR2 and HBR3 but maybe this is a VRR issue (edid will tell)

Re: [SOLVED] Weird video artifacts at 144 Hz with NVIDIA open driver

Is 3440x1440@120Hz ?

Display supports continuous frequencies
/sys/class/drm/card1-DP-3
Display supports continuous frequenciesSo kwin deems the XMI output VRR incapable but 3440x1440@144Hz also exceeds the 600MHz limit (so seems a VRR thing) - can you re-enable VRR?

2560x1080@144Hz stable
3440x1440@120Hz unstable
VRR on ultrawide is not avalible, only on secondary display and this change nothing when I turned on.
