Since updating Photoshop CC to version 19.0 (Mac Pro late 2013 version 10.13.1) the scrubby zoom looks chopped when in full screen mode.
The zoom is not smooth anymore and the image gets re-centered while performing random things like selecting a layer or saving a file.
Looking for a fix.
Same issues for me. Happens more at a certain zoom level, mostly when I zoomed out and can see the whole image.
Also if I zoom out using scrubby zoom but don't release my pen the image flickers around my screen.
Looking for an update to your update
