I have a dual boot system Windows 10 (22H2, driver 527.37) and Arch linux (6.0.12, driver 525.60)
In the last monthes I encountered a lot of distortions under linux, especially on youtube.
Examples for that are
see screenshot problem1
Problem: rings around the girl, in Firefox, Librewolf and Chromium
Behaviour on windows: the same
youtu.be/5yUr4LJFIuc?t=71
see screenshot problem2
(distortions in gray/white/brown on top of the door)
Behaviour on windows: Windows does show the video correctly, both in Edge as well as in Firefox
That might be, but as far as I see, there is no working solution (either).
One question: As it might only be visible on my screen (and only for me in this thread): Can you clearly identify the effects I mentioned in the pictures?
And if yes, does it make sense to merge this thread into the other one?
Downgrading the driver to 515.76 - as suggested in the other thread - did not resolve the problem.
PS Further downgrading to 515.57 resulted in an unusable system. I guess, that driver version did not support the 1650. Am I right? Is there somewhere a list of drivers versions that are supposed to support the 1650 ?
Yes, in your initial posts I was not able to see any issue on my monitor, the new fotos show the banding.
According to the changelog, the 1650 is supported since
2019-05-07 version 418.74
So I guess 515.57 just didn’t build on your kernel. Rather use the 470 legacy version as a check point.
Unfortunately, downgradenvidia-dkms nvidia-utils
further than to the already unusable version 515.57 is not possible on my system (which is kernel 6.1.2 now).
I also tried that with the lts-kernel (5.15.86) and nvidia, nvidia-lts packages instead of the nvidia-dkms package.
I managed to get two backup system (on my hard disk and an USB stick) running with older drivers
Kernel 5.19.3 nvidia 515.65.01-2
Kernel 5.15.86 (lts) and nvidia-dkms 470.74
For both combinations, the banding is much less (but not gone) for the first example, and it’s almost gone for the second example.
If this was a problem with the dithering settings - like the people in the other thread say - then why does it still appear, if I completely disable dithering?
Addon: The (current) Windows 10 driver 527.37 has a similar problem, although the distortions are smaller or at different time frames of the given videos.
I tried all combinations that are possible in the Dithering controls.
I even tried to switch Dithering off.
Right now, they are set to Auto, Auto, 8 bpc. Before that they were
set to Auto, Temporal, 8 bpc (Hardware default was Auto, Auto, 6 bpc,
for some unknown reason)
There is indeed a difference in the effects on screen, but some distortions are still there, no matter what settings are active (under Linux as well as under Windows)
Addon: If the 1650 is connected to the monitor with an HDMI cable instead of a DP cable, then the settings change to Auto, Temporal, 8 bpc, and the output has less distortions.
