Digital scramble

[magnificent_dayB839]

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?

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.

This sounds like a known bug:

I upgraded to Sequioa 15.2 and the issue went away.
