Hello everyone,
I’ve installed a fresh copy of Manjaro with KDE Plasma and while everything worked perfectly out of the box, the display - not quite.
I have a ViewSonic XG2402 1080p 144Hz monitor and GTX 1060 GPU (with proprietary drivers) connected via DisplayPort. After trying to change the refresh rate to 144Hz, the smoothness seems fine, but I can visibly see some weird grayish lines (sometimes looks like a grid of big grey pixels). And the screen itself seems to get a bit lighter. I only see these lines in darker colors with only one exception - I don’t see any of the lines in black color. The lighter the colors are - the harder it is to spot them.
I see this issue with anything above 60 Hz. The higher the refresh rate the more visible it gets.
I’ve tried taking a screenshot and looked at it via another computer/phone - didn’t see those lines.
Since I have windows on another SSD, I’ve booted that up and couldn’t see any lines there either.
I thought maybe I messed up my installation so I’ve booted via live USB twice, one time with open source and the other time with proprietary drivers:
- With the open source drivers the higher I went with the refresh rate the more it started to flicker (observed the same results in normal installation)
- With the proprietary drivers - those same greyish lines appeared.
I don’t know if you’ll be able to see it, but I’ve tried capturing that with my phone. Here are those pics:
