Apparently, I can now finally reply. Tried to upgrade to the newest driver today, but the issue persists. So I think that it is safe to say that this bug affects both 520.56.06 and 525.60.11. 515.76 still works correctly tho.
Just wanted to say that this is probably related to the high refresh rate. Because most people who experience it have a high refresh rate monitor and the issue gets progressively worse the higher refresh rate you set. (60hz - basically unnoticeable; 240hz - horrible)
After installing the 525 driver I had a lot of problems with one of my systems. For some reason the driver changes some settings in the Dithering Controls section. With the 515 series I had all the options on Auto which causes no problems at all.
After I installed 525 I had to mess with the settings because I noticed glitches when dragging a window. I had to change Dithering to enabled and Depth on 8 to fix that problem, however when I use 525 I get a lot of color banding. Another problem that I noticed is that if I go to the Information tab the new driver only used 2 lanes instead of 4? Also I believe that the new driver is messing with the color settings. I reverted back to 515.
Hello
I admit, it is better but in the darker places are still pixel artifacts :( I think in previous drivers (before the issue this pixel artifacts wasn’t there)
current driver 525.89.02
Linux-x86_64 (manjaro Gnome version)
3440 x 1440 120Hz GSync Enabled - via Display port
AGON AG 352UCG6
CPU: AMD Ryzen 7 2700X (16) @ 4.000GHz
GPU: NVIDIA GeForce GTX 1050 Ti
Asus PRIME x470PRO
Nvidia setings: Dithering, Mode, Depth on auto [enabled,None,8bpc] [I have more screen shots but can’t add ]:
While looking at it closely, I see that unfortunately, you are right. It’s very slight, but it’s there. At least it is usable now. Still, it would probably be better to investigate.
Updating to 525.89.02 fixed the banding issues but brought back random freezes. Oh well, time to google that GPU clock kludge again and see if that helps :)
After updating to 525.85.05 this issue still persists for me.
With dithering disabled in Nvidia X Server Settings, I get ugly banding in gradients, with dithering enabled, the gradients look OK. I tried my best to capture this with my phone. https://imgur.com/a/W8iPbmv
The problem with this is that with dithering enabled, I see moving patterns in dark areas that look almost like moire patterns. I use my PC mostly for programming in a dark IDE and this is very distracting. Unfortunately this is almost impossible to demonstrate. It is barely visible on camera if you don’t know what to look for, because filming an LCD screen is hard. And obviously it does not show up on direct screen recordings. I will try and obtain some kind of HDMI capture device to record it.
Turns out I am an idiot and confused 85 and 89. Waiting for 89 to show up on Ubuntu then.
