We're sorry to hear about this, could you please let us know which version of Photoshop are you using and which operating system are you working on?
Also, could you try resetting the preferences of Photoshop and let us know if it helps?
Preferences in Photoshop
Good grief. That was it. Not sure what I did... I rarely touch the preferences. And it also only happened once I moved to the super ultrawide. Go figure Thank you.
I expect you are aware that we had a few posts with similar issues after the 19.1 update. In most cases I think a Preference reset fixed it.
The issue has returned. And it only took a couple of days. I don't want to be resetting my preferences every couple of days to deal with this problem. I hope Adobe can manage to fix this.
