It would be better testing something free of charge first.

As this issue cannot be reproduced in my side, the root cause could be in
differences between us. Configurations for X11, OS versions, what's installed
and how configured, and finally, hardware.

I'm testing 580 series of drivers on:
  ThinkPad P52 with Quadro P1000 (notebook) with 4k panel (internal and
external)
  Minisforum MS-01 with RTX A400 with external 4k monitor

On both hardwares, tested on stable/15 (and main if my spare time allows) that
are nearly up-to-date at the moment I'm testing.

Intel iGPUs are explicitly disabled via UEFI firmware on both hardwares.

External monitor is actually single JAPANNEXT JN-IPS2380UHDR-C65W-HSP that is
capable of displaying 4k in 60Hz VSYNC and having 1 DP, 1 HDMI and 1 USB-C as
input.
RTX A400 on Minisforum MS-01 is connected via miniDP on RTX A400 itself.
ThinkPad P52 is connected via USB-C, which is recognized as Internal Display
Port by xorg.

Using up-to-date (at build time) master (aka latest) branch of ports tree to
generate sane diffs to submit.

Using graphics/nvidia-drm-612-kmod-580 with
graphics/drm-612-kmod,x11/nvidia-kmod-580, x11/nvidia-driver-580 and
x11/linux-nvidia-libs-580.
