Opacity mask editing mode is broken, changes made are not visible unless Clip / Invert option is selected
I am experiencing a very new issue with Illustrator: when I draw something upon an opacity mask, the effect is not shown in real time.
Never happened something similar before.
I'm trying different settings with CPU preview, and also the relevant flag in the preferences (Draw and modify in real time, under "Performance" tab, hte last line) but does not seem to affect.
This has been happening since the latest update.

Same issue for me, since the latest update.
I also published a bug report yesterday. -

I have the same issue. The transparency mask doesn't update in real time and the only solution is to keep clicking on the Invert Mask to see the change which is very inconvenient.

Interesting that you posted this today, I discovered the same issue today as well. Switching to Outline Preview and back to GPU works as a temporary fix but it's really tedious.

Since V25.1 Vector Masks don't update anymore in realtime. A checkbox OnOff-Click (i.e. on invert mask) within the Masks/Window forces a redraw and the mask is rendert as expected.
OS: Catalina and Big Sur
Illustrator 25.0.1 works fine regarding issue
