Glitching White and Black Squares after Magic Mask

Hey I was wondering if anyone else was experiencing glitching after using Magic Mask? It looks as though pieces of the image are missing and black and white squares flash around the edges.

Have not had this problem and have used MM a lot! Have you tried doing the clip in Fusion stand alone? Out of curiosity are you altering the mask using erode/dilate?

Likely a GPU issue I guess

Is that flashing both in Fusion viewer and timeline? I'd suspect NaN or inf pixels produced somewhere in the processing chain, possibly by doing a division by zero when unpremulting the data.
