Mouse Pointer/Curser Lag over any open file in PhotoShop CC
I've had this problem for almost 2 months now. It has persisted through updating my MacBook Pro from the old iOS to High Sierra, and it has persisted through updating my PhotoShop CC from 2017 to 2018.
The mouse cursor/pointer lags terribly when it goes over any open file workspace area in PhotoShop.
- It lags over the art itself, and over any open space between the art and the edge of the tab or window.
- There is no lag over the UI areas.
- The amount of lag is inconsistent. Sometimes it's just a little slow, other times it take a lot of shaking of the mouse/stylus to get to the edge of the image if the cursor is trapped inside it.
- It lags in any tool, but if it's a click tool (like selection) the lag stops immediately upon clicking to select.
- The lag is the same with a mouse or a stylus.
- The lag stops temporarily if I do -> Preferences -> Performance -> Advanced Settings -> change dropdown to "Basic" and then RESTART PhotoShop. But it will come back again after a short time.
Here's a YouTube video someone else posted about it: Photoshop CC 2017 Mouse lag problem - YouTube
This is really maddening, and it hasn't gotten better with any updates to PhotoShop or the iOS since it started.
Please Help.
