Local adjustments: Mask rendering broken

Hi all,

I am trying to create a mask for a local adjustment using the graduated filter. Next, I erase some of that mask using the brush tool (and holding Alt key). Consistently, the rendering of the mask permanently breaks in such a way that only see fraction of the actual mask and some boxes spread around the image canvas in areas the mask never was in.

See attached screenshot for more details.

Effectively, I can’t evaluate anymore from mask display what the mask is.

I’ve restarted PL, but that doesn’t change anything.

I was about to post a new topic for the exact same issue:

It happens when I select a local adjustment with a brush mask and I scroll or move the picture. It also happens when I erase a part of the mask (same problem as the OP).

I’m running the latest PL5 version, on a M1 Macbook Pro.

I should add that not only is the mask rendering broken, but the actual mask seems to be broken as well, applying only to the small squares shown in blue.
