Has anyone had an issue with a file locking up while using quick mask? It happens to me mainly when zoomed in and moving arond in the file. It locks up the file and have to save it and close the file and reopen to continue. It doesn't lock up Photoshop, just that document I am working on.
Started a couple of upgrades ago. I downoladed the newest upgrade 22.2 and still happening. Maybe even more now.
The problem could also be a corrupted Preferences file. Usually that file travels with the upgrades. I'd try a Preferences Reset, but before we do this, back up your custom brushes, workspaces, everything in the list.
