Hello, could you post a screenshot of your interface when this happens, Cmd+Shift+3

also, please post the contents of Photoshop's Help>System Info... menu, so that we get to know your OS, its version, the exact version of Photoshop you are running, the date of the GPU driver, etc.

Po zaznaczeniu obiektu i maskowaniu pedzel zostawia smugi, nie działa zacina się i zostawia piksele. Co mogę w tym wypadku zrobić?
