Black Artifacts/Glitches with adjustment layer
I keep getting random artifacts popping up on my projects, its caused by an ajustment layer with effects on which I've narrowed down to be the Gaussian Blur and Brightness & Contrast. Having both active causes the artifacts, but having only one stops them. My project used to be fine, I had the same effects but no artifacts, I can't think of anything I specifically changed. The artifacts are also inconsistant, they are different each time, sometimes they'll be there, but if I rewind and replay, they'll be gone or different. I rendered it out and even the rendered frames had the glitches
The issue can be seen below:
The black bars across the screen are not supposed to be there

It is supposed to look like this:
