When using the new masking tools, I have to restart Lightroom after every 2 or 3 edits because some functionality stops working. I don't know if it's a bug or if it's me doing something wrong, but I'm getting frustrated!
Anyone facing the same issue? If so, did you manage to solve it and how?
Have you considered resetting the preference file? Be aware that doing so will revert various settings to defaults. Resetting the preference file is Adobe speak for moving or deleting the preference file with LrC closed, then upon restart of LrC the file gets created fresh. A corrupt preference file will lead to buggy behavior.
