Vertical lines across rendered footage

[juang98277388]

I layered two video clips on top of each other. I added a crop effect to the top clip so that anything not masked out will show the underneath clip. However, once I hit render, vertical lines appear across the footage. These lines stay on the footage even after I export it. I don't know if this is a problem with my sequence or the version of premiere I am using. I use premiere pro CC 2019.

GPU driver issue, clearly. Go to the manufacturer's site and make sure you are on the latest driver. If you are, roll back one.

And/or try Projects Settings of Mercury Acceleration/Software Only.

Thanks Neil. I switched my video render settings to Software only and it fixed the problem!

What's your GPU and the driver number in use? That determines whether Premiere works with it or not.
