Blue glitch in Program monitor when editing properties of Key

Context

I have a simple project with a single sequence that has two populated video tracks. One clip duplicated onto two tracks.Video clips are both 1080p and 24 frames per second (shot at 240 10x slow-motion on a Fuji X-H2).

The top track has two effects which I have added. One RGB Curves and one Color Key in that order.

Problem

With the above project, when I do any of the following:

  • advance frames in the Program Monitor (single frame or played with the play button)
  • Edit any properties of the Effects

I get this result:

The Program Monitor glitches and shows a display of blue random boxes.

Before activating

After activating 

Additional Info

It's probably at least a little difficult to see my issue fully here because the before image is not a typical scene. It is supposed to be a high contrast green and red scene. The blue boxes are the culprit I am trying to eliminate. 

This is what I have tried in attempt to remedy this issue

  • Verified that the system was getting sufficient RAM. 52GB of the total system 64GB
  • I looked for, but could not find, any other controls to maximize/optimize system resources
  • I tried a Luma Key instead of a color key with the same results
  • I tried exporting the project, which does result in the correct/expected results without the blue glitch, but this is not a sufficient workflow for tweaking Key properties

I can post other system specs if that would be helpful. I assumed this would be sufficient resources but I am a novice to video editing so I could be wildly wrong.

Thank you for responding. Disableing the GPU does not seem to correct the issue.

I have found a woraround though. Changing the playback resolution (from 1/4 to 1/2) in the program monitor fixes the issue for me.

Have you tried setting the Mercury Acceleration option in Project settings to software only, turning off GPU use?

 

If that fixes this, then it's a GPU issue.

 

What is your GPU and the driver it's using?

Everyone's mileage always varies ...
