After Effects + UltraGear 38GL950G-B 38" | Getting very low FPS in the actual AE UI

Question

So I recently bought an LG UltraGear 38" monitor. I'm noticing though whenever I'm in After Effects or C4D the FPS in the software itself drops to anywhere from 15-32, I specifically feel and see this in the mouse cursor as well as when I monitor the FPS with a counter. Whenever I hover over the actual composition viewport the FPS in AE drops from a locked 144 down to 15-32. The second my mouse leaves the composition panel and I click in to say, the project panel, it shoots back up to 144 and stays locked there and the everything feels smooth again. This problem happens in both versions of AE I use which are 2020, and 2023. 2023 will also flicker occasionally in the viewport. It doens't flicker to full black, just these weird soft flickers that happen as I scroll through the timeline. This does not happen in 2020, but I also noticed it happening in C4D as well. None of these issues were present with my 2 x 2k 27in monitors I had before.

I have no idea how to solve this but I imagine the monitor must be playing some role here. I'll paste tech specs below but I do have 2 x 2080s so I'd be suprised if it was cause my PC can't handle the monitor.

Try to deactivate g-sync.

AE was made for 1993-2010 hardware, and needs patches to make decent use of anything newer. throw it a curveball like threadrippers with lots of cores, or SOC's, multi-CPU systems, GPU's, etc, and it starts having conniptions. Things like monitors that communicate with new hardware using unusual or non-production (like gaming) drivers are gonna give it some extra trouble. I think gsync is interpreting something about the preview oddly. I've gotten some nonsense too, like the preview disappearing, to show that all the inactive tabs are actually hidden beneath it.
