Digital scramble
Premiere 25.1
iMac OS 14.6.1
While working on the video effects of a clip - ultra key, opacity mask...etc, the program monitor will have a striated digital scramble that flutters, and after a while corrects itself. This happens often. I have plenty of memory assigned to Premiere, GPU Accelerator is selected, cache has been cleaned repeatedly, content has been reopenend in new project and new sequence.
Any thoughts?
