Not the flickering.
The performance level is supposed to go up to P2 on a multiscreen setup, but seems to do not on the new driver (there can sometimes be a short delay, so checking a couple of times or "nvidia-smi -l 1" should ensure that this is really not happening)If the level stays at P8, see the linked nvidia.com thread and if you're not (yet) involved, get it and share your findings.
+1 will hopefully draw more attention and the performance level situation is probably very helpful in order to fix this.
I meant the state staying at P8, not the flickering
I will reply to the NVIDIA thread and see if NVIDIA cares

@cozyGalvinism good find on the refresh rate. I have a very similar setup with a 144hz and a 165hz monitor. Setting them to 60hz does seem to stop the issue. FWIW I'm using dwm as my WM, not KDE.

Just to confirm that this is related to the refresh rate. I have also a multi monitor setup. But this also happens without an external monitor attached. The Laptop has a 4k display but for some reasons (scaling is not straight forward for different applications) I am using a lower resolution

If I choose
3840x2400 60.00 +
no flickering is observable, but xrandr doesnt suggest me an even refresh rate for 1680x1200 (where flickering is happening)
I didnt have this behaviour before the last update.

Hi, I just wanted to know that the problem still persist. Anyone has an idea how I can takle it down?
Often the "flickering" is quite slow: it moves around 10 % of the image of the screen from the right side and adds it to the left side of the screen. Sometimes it stays like this for a split second and other times for 1 or 2 secs. Unfortunaltely I dont see a button to add an image.
Greetings

I don't think you're hitting anywhere near the same issue as the OP (different GPU, different conditions)
The Laptop has a 4k display but for some reasons (scaling is not straight forward for different applications) I am using a lower resolution
If I choose [the preferred modeline] no flickering is observable, but xrandr doesnt suggest me an even refresh rate for 1680x1200 (where flickering is happening)
Open a new thread, post your xorg log, https://wiki.archlinux.org/title/Xorg#General and explain what
xrandr doesnt suggest me an even refresh rate for 1680x1200 (where flickering is happening)
is supposed to mean.
On a limb: remove xf86-video-intel.
