Hi all, i'll cut straight to the point then get into the background - if you own an iiyama GB3466WQSU please could you do the 30 second test described below (See "The Test" section) and report the results back to me?
I am running out of ideas on what may be the cause of this issue and still don't know if this is an issue with my settings, my hardware, or a fundamental issue with the panel.
Background
In October i bought one of these monitors, it's been great except for one issue - i have white horizontal lines (1 pixel tall - very small but it is noticeable!) on various bright colours at 100hz+ (seemingly only on static [I.E Desktop] elements, but not sure it's exclusive). I have included pictures trying to show this issue below. It's not the worst issue ever, but it's annoying, and if it's a problem for everyone, maybe iiyama can get some useful input on a monitor issue.
What i have already tried
The Test
If you can't see the image very well, this link may help: https://pasteboard.co/JHFaFiU.png
Thank you!
(by the way, i'll also be interested if you cannot see the problem i am talking about, then i will work on making clearer images but it is very hard to capture on camera)

What i have already tried
- I have the latest Monitor Firmware, no fix.
- I have tried 3 different DP1.4 cables, no fix.
- iiyama have given me a new monitor under warranty (great service btw), no fix.
- I have bought a completely new GPU, CPU, RAM, Mobo since the first monitor and started a completely new Windows 10 install on a brand new SSD, no fix.
- When i did the fresh PC build, i checked this problem first (switching between refresh rates) without anything installed (except whatever drivers windows found) and the problem still existed at 100hz+.
- After 4. i installed the latest Nvidia Drivers, no fix.
- I've also messed around with the monitor settings but in no structured manner (I.E turning on/off freesync, HDR, changing colours etc).
- May not be relevant but i've also done a Mobo BIOS update twice with my new Mobo, no fix.
The Test
- Make sure you are running at 144hz.
- On Windows 10 go to Start Menu > Settings > Personalisation > Themes > Colour
- Set Choose Your Colour Drop Down = "Custom"
- On the "Windows Colours Pallete" choose the blue which is third down on the left. It is called "Default Blue".
- Scroll down and make sure under "Show the accent colour on the following surfaces" that "Title bars and window borders" is checked.
- I don't think it matters but i also have "Start, taskbar and action centre" unchecked, as well as Transparency effects ON.
- Finally, open any window that uses the windows theme and drag it to various places around the monitor (i found this problem seems to be slightly worse at the top of my monitor), in my examples i have always used File Explorer but i can see it on all windows and even some of my start menu tiles.
- Look at the title bar - CAN YOU SEE WHITE LINES LIKE MY EXAMPLES BELOW? (You can also try switching between 60hz and 144hz to see if theu disappear/reappear)
