<p>In premiere pro when I set the renderer to GPU Acceleration (CUDA), for the timeline and on media encoder export, half the video is completely messed up with lots of pixelation artifacts when I switch on any effect or make a change in the lumetri colour panel. Any solutions?</p>
<p>I'm running premiere pro 2020 v14.3.0 and have the GTX 1060 3GB GPU with Nvidia drivers 451.48.
I have also tried reinstalling both and deleting all the cache to no effect.</p>

Hi this issue happens in the timeline window as well as the render export only when GPU rendering is on making me think it's independent of the export settings. I use h.264 full hd 1080p export preset.

Oh yikes - could it be that the footage is corrupted? What happens when you use a different clip in the timeline?
