What is going on with my PC?

I have a Dell S2417DG and a GTX 1070ti. Is this issue i'm seeing related to the monitor, graphics card, or something else?

restarting the computer and monitor fixes the issue temporarily.

Have you tried updating or changing the graphics card drivers, and is your monitor running at its native resolution?

Running latest drivers from Nvidia and running at native 1440p at 144hz. This has persisted over at least 3 driver updates. The 165hz overclock is not on. Originally I turned off power saving mode on the monitor as it usually happened waking from sleep, but now it happens regardless.

Seems like a row of vertical pixels are switched, but it's really hard to know if it's the fault of the monitor or GPU, quickest way to figure it out is to try your iGPU instead, or a different system entirely.

Have you tried using another pc or something else to see what happens? See if for wathever reason windows  changed your native 1440 for upscaling
