Lumetri Color Glitching Bug

Is anyone else able to replicate this issue? Does it happen on a Mac, or with non Nvidia graphics cards?

Running Lumetri Color with any value of "Whites" or "Blacks" other than the default 0 in the Basic Correction section causes garbled garbage white lines on the far right of the screen. I'm having this happen with footage that's 4676 x 2338, but I'm pretty sure that's not the only resolution affected.

Steps to reproduce this bug:

  • Create a sequence in Premiere that has these Sequence Settings: 4676 x 2338, Square Pixels (1.0), No Fields (Progressive Scan)
  • Create an adjustment layer that matches the sequence size and place it on the timeline
  • Add Lumetri Color and change "Whites" or "Blacks" in the Basic Correction section to anything that's not 0
  • Place any piece of footage underneath, and make sure that it's big enough to fill up the entire frame (the bug will happen on native 4676 x 2338 footage, as well as anything you scale up to fill the frame)
  • Notice the glitching white pixels on the right-hand side of the screen

This glitching shows up in the final product, if you encode at the same frame size (4676 x 2338), so you can see the bug in action here:

  • GTX 1080 with up to date drivers (also affects older driver version 388.13)

I see the same thing with various still images in a 1080p24 timeline. It goes away if i turn off CUDA or change it to Open CL or Software only. It can be reproduced to 100% on new projects. This image is from a new project created in 12.1.1 #10: http://privat.bahnhof.se/wb792290/cuda-lumetri.png

For me it happens "only" when CUDA is enabled, Lumetri added to the still image and when i use the Whites and/or Blacks sliders in Lumetri. Any other settings in Lumetri seems to be ok, but once i start to use the Whites and/or Blacks sliders in Lumetri it triggers this on some stills.

On my laptop i can switch between CUDA and Open CL, but not on my workstation so i am stuck.

I am working on a large project with hundreds of still images and they have worked before. Some stills show this glitch, some don´t. And yes, as already stated it will show up in the exported media no matter what final codec you use...
