Screen glitches and flickers on OC 0.6.1 Catalina 10.15.6

Screen glitches and flickers on OC 0.6.1 Catalina 10.15.6

Hey, it's me again, guy who can't get his act together in the Hackintosh scene.

Fortunately, I do have a working HackBook though! I have macOS Catalina 10.15.6 using OpenCore 0.6.1. Almost everything worked fresh after install except trackpad, iServices, a glitchy headphone jack, and the reason I'm making this post: screen glitches.

While using my HackBook for a little while, there seems to be random points where the screen just turns off for a second or two (sometimes twice or three times in a row, such as when I'm writing this) and then comes back on. This isn't too annoying, but I'd prefer to have a fix for it.

Another visual glitch, however, is so much more annoying. I can't open either Discord or Chrome without having all kinds of screen distortion, tearing, and even the aforementioned flickering. It's frankly obnoxious and I experience these things until I quit the app causing the issue.

Has anybody else had this issue? I've seen a few people ask online, but that seemed to be an issue with the RTX 1080 (IIRC). Of course, I'll post my specs, but I'll also attach a photo of my EFI tree for any of you to see if anything in there is faulty. Thanks in advance!
