Hi guys,
have not written in a while because I fixed the problem for me on Linux and Windows.
I noticed when I install 4.15.0-65-generic Kernel on Ubuntu 18.04 it is making all of my computers better. However it is not "perfect" on e.g. ATI cards. NVidia is still the best for me.
When I install 4.15.0-88-generic or higher it gets significantly worse. Have not checked the kernels in between. Would be interested in what code change did this and if this is configurable in newer versions.
Hope that helps anyone.
Best setup:
Ubuntu 18.04 Kernel 4.15.0-65-generic
Quadro P600 (dithering disabled in driver)
Dell 2408 connected with DP
But also noticable on a Thinkpad W500 using an ATI GPU and a Fujitsu laptop running on Intel
EDIT:
Just upgraded the NVidia driver from 440.59-0ubuntu0.18.04.1 to 440.64-0ubuntu00.18.04.2 and it got worse.
Had to install 4.35 and it is better again.
EDIT 29th of March:
Still not as comfy as my Windows 10 setup. Was reverting to Nouveau and linux-firmware version 1.173.12. 1.173.16 is worse. However with this version I cannot suspend as the system does not get up anymore
EDIT 31st of March:
Ok, I made it better again using the NVidia driver. Secret here was to disable dithering (which is obvious) but also "Sync on VBlank".
