I downloaded Vegas 18 on my laptop with just Intel HD graphics and a i3 and albeit slow to render and edit, I never had any graphical issues or rendering output issues.

I switched over to a pc rig I bought from a friend a month ago, and when I got Vegas 18 on it the first issue I noticed is that the screen would glitch out at the top, and in my preview the video would randomly have green overlay flickers. I simply turned off GPU acceleration to fix it, and it was all good.

Fast forward a month later, and I'm editing footage I downloaded from my Twitch profile. It's all going fine until I make a few cuts and then suddenly, the glitch starts happening again. The top of the screen glitches out when I move around, and the preview has green flickers. I did some research and found nothing. I went into Internals settings and set the OpenCL interop to FALSE like recommended, and that fixed it. I was able to edit the entire video without the issue. I even switched GPU acceleration backon for the extra power, and it was all fine.

Then I went to render, and it started again. So, I stopped the render, turned GPU acceleration off, and tried again, and it still kept doing it. I let it render out thinking maybe its just a glitch with the UI code or something, and my final rendered video is littered with the green flickering.

Flickering seems to be a problem for a lot of people, but this bug with the actual UI glitching out seems new when I try to search for it. I'm attaching an imgur link of what it looks like. https://imgur.com/4Hbfe5h

I have tried everything above, and it seems like its picking and choosing when to work and freak out. Anyone have any ideas?
