I am running Nvidia Prime setup on Centos 7.4 on Dell Inspiron 7559 (UHD monitor + GTX960M) on 384.98 drivers and few days ago strange artifacts started to appear on my screen after getting to X server. (They are not present in grub/bios.)
This is photo of the artifact:
And here is visualization (I just drew it in Krita to show how it looks like):
They are mostly static, but when I start to move windows they are twinkling a little bit.
Usually when I restart GDM or change resolution of the screen the artifacts disappear, but they always appear again after restarting the computer.
When I take screenshot of the screen, the artifacts are not present on the picture. First I thought that it is problem of my system. So I installed Ubuntu LTS 16.04 with NVidia-prime and 384.90 drivers, but I got the exact same artifacts, but on another place on the screen. Then I tried to install latest 387 drivers on Ubuntu, and the problem is gone, no artifacts are present - Thats why I think that it is problem of the current drivers, but maybe it is hardware fault. I am not sure.
Here is bug report log:
Please could you help me to solve this problem?
Thank you very much and have a nice day
