Airbrush is lagging behind the cursor. Just the airbrush. Pencil, clone and healing brush are fine.


At first I assumed it must be a Wacom issue, but it also happens when using the mouse. Also: the brush in PS CC 20.0.9 is working fine on the same system with identical settings.

Link to a screencast showing the issue: The brush is a few inches behind the cursor. This is on a small file.

Mac Pro 5.1, 48GB, Radeon 7970, OSX 10.14.6 (as far as it will go)

Back to PS CC 20.0.9 for now.

From your video, it looks like smoothing is cranked up to 100%.  That will introduce lag.  Turning down the smoothing will dramatically increase the speed and close the distance.
