Cyan Artifacts on ProRes with Alpha

[d29500328]

After reopening Premiere, I've been getting these cyan artifacts on my Prores+@ content. Example 

My sequence settings as it relates to video previews:

Quicktime - Apple ProRes 4444, with Maximum Bit Depth and Composite in Linear checked on. 

I'm currently on Adobe Premiere Pro 14.3.1 (Build 45)

Hi davida29500328,

We're sorry about the poor experience. Are you still experiencing this issue? Also, could you also please confirm if you are getting this preview issue in Premiere Pro v14.3.2?

Thanks,

Sumeet

Try unchecking Linear ... see if that helps. It might. If not, then uncheck the Max Depth also.

Any particular reason the previews are 4444 as opposed to 422 or 422HQ?

That did the trick. I unchecked everything and changed the Video Preview File Format to QuickTime - Apple ProRes 422 HQ.

The reason it wasn't set to that by default is because my footage and sequences were all in GoPro Cineform. I started to switch to ProRes 4444 because it encodes 8-bpc + alpha, and so my video previews were set to that.
