Please uncheck Use graphics processor from Photoshop preferences by going to Photoshop > Preferences > Performance.
Then Relaunch photoshop and try if that works.
Thanks for the advice, so this week I tried to work with the Graphics Processor > Advanced settings set to Normal.
The behavior of the cursor was the same, but not that often, I think. Next week I will work with Graphics Processor turned off, like you (Bahaar Khan) said.
See you next week. Let's hope it works.
So, I tried a whole week with that setting unchecked, it's the same.
Sometimes I can work for hours with nothing happening but when it starts, oh boy... I can barely move my cursor from one side to another.
Do you have a Wacom tablet connected?
Nope. But, I forgot to say something, today my working monitor died, I have the iMac and a bigger Dell. Today the dell died and until replacement I'm left only with the imac.
I'm curious if it will still happening.
I'm back with answers , after two weeks of working only on my 21" iMac, with almost zero problems, today the new display has arrived, a 28" 4K Dell 2017 model.
Aaaaaand we're back..... in photoshop the mouse keeps stumbling upon..... who knows? and in Indesign when I grab an object (text box, object, picture) to move it around my monitor goes black for 1 second or so.
So, f********* u Apple for this, or Adobe, I don't care who is to blame, all I know is that the forums are full with these errors.
For the ones that don't know yet, the indesign bug dissapears if you make the Mouse Cursor bigger in "system preferences".... yeah, really.
