NVIDIA 520.56.06 Color banding and animation issues

• [NVIDIA Bug Report] Color banding and animation issues with 520.56.06
• [Manjaro Forum] Nvidia Dithering mode no longer working after the nvidia 5.20 driver update

Current (not so good) Workaround:

• Open nvidia-settings
• Select the problematic monitor under the GPU Tab (e.g. DP-0 - (LG ...))
• Under Controls, change Depth to 6 bpc (or play with the Dithering Controls)

NVIDIA already replied to the Bug-Report, so there is a good chance that this issue will be fixed with the next NVIDIA driver release.
