No changes displayed until I zoom. How to fix.
Since the latest update of Photoshop I have a bug which has made it unusable.
When ever I make a change to a document (not all of the time but most of the time) it looks like nothing has happened. If I use the zoom tool suddenly the changes appear on my document. This basically renders my photoshop unusable.
It happens during any selection, masking, undo-ing, shape drawing - but strangely not for some tools like the paint brush.
It also doesn't display the errors in the layers palette.
Deleting preferences doesn't do anything.
I have un-installed and reinstalled which fixed the problem for about half a day.
I have turned off 'use graphics processor' in preferences - no change.
I am running OSX 10.13.3
Intel Iris Graphics 550
Late 2016 MacBook Pro
Can anyone help me please!
