Hi there,

I'm experiencing a bug that pretty much renders my Photoshop useless unless I'm using an external monitor. Note that I primarily use an external monitor for my design needs and when working in that set-up, this glitch doesn't happen. However, whenever I'm working directly from my MBP's screen, this consistently happens. Whenever I zoom an image more than 100%, part of the image either goes black or green as shown in the attached video

 

Has anybody else experienced this and/or have any possible resolutions?

 

Thank you.

Hi @juicetinking  Can you try this: go to Preferences >Technology Previews > enable Deactivate Native Canvas. Quit Photoshop and relaunch. ~ Jane

@juicetinking , do you see green screen issues when using Photoshop without ever attaching an external monitor?

With my external monitor hooked up, a similar bug would happen but instead of green, the entire canvas would either go black or parts of it would appear blank white when zooming in and out (to certain scales). Without the monitor hooked up (just working from my MBP’s screen), it was exclusively showing up as a green glitch. Enabling the checkbox ‘Deactivate Native Canvas’ has so far eliminated all of this behaviour with both the external monitor hooked up and just working exclusively on my MBP’s screen.

When Photoshop launches, it sets its default display to whatever screen it first draws to. If you launch Photoshop without the monitor connected, then quit Photoshop, your laptop will be your default display. Then, if you connect a display while Photoshop is running, then move the app to the other display, you've changed the display to your external, and that confuses Photoshop.

 

The next time this happens, quit Photoshop, set up your hardware and displays the way you want them, lauch Photoshop and put it onto the screen you wish to use as your 'main' display, then quit Photoshop. The next time you start Photoshop, it should be trained on the correct display and the green should not happen.
