Preview showing white and black artifacts when paused

Got it and thanks for the details @Aaron36104484dbcp. Issues like this are usually GPU related. Are you able to update your macOS to Sequoia? There have been previous reports of similar problems here, and updating from Sonoma to Sequoia was a fix.

@Dani_V. The only effect it has is noise. I will try exporting with those other settings. And yes, it's an mp4.

I believe it may be an issue completely outside of the footage because I just reopened the project after a night of having my computer asleep, and it's back to normal. But when it does show up, it seemingly "infects" every project that I have open at the time. Could it have something to do with storage space or something like that?

Thanks

Thank you for the additional screenshots @Aaron36104484dbcp! Does this overlay have any effects or filters added? If you go to Preferences > Media, can you try disabling 'hardware accelerated decoding'? And what are your export settings? Can you try exporting with Software Encoding instead of Hardware Encoding under Video > Encoding settings? If you think it's specific to the overlay (this is an .mp4 too right?), you could also try to 'Render and Replace' the file.

@Dani_V. 

Attached are screenshots of the specs for Premiere and my Mac.

All file types being used are MP4. There's a transparent version of the issue when exported, but only when the one overlay is in the video. Looks like it might be the black parts of the bug showing up. I included a screenshot of that as well.

And no, the issue doesn't show up when playing, only when paused on the timeline, with the exception of the export.

Exported video when the one overlay is on screen.
