Image canvas flashes or flickers while making adjustments in Photoshop 21.2 on macOS 10.15.5

[bhandjy]

When I try to make adjustments to an image, e.g., brightness/contrast, exposure, etc., the image flickers as I move the slider up or down...very annoying and makes it difficult to see what I've done versus what was. I tried turning off the graphics processor to see if that would make it stop but it didn't. Any advice is appreciated. And FYI - I have macOS Catalina 10.15.5, the latest version of PS CC 2020, and just did the upgrade from Nik Collection 2 to 3. John

Hi,

We're sorry about the trouble with Photoshop. Since when are you facing this issue?

You can try toggling the option for Legacy Compositing from Photoshop by going to the Preferences, then Performance. Once done, quit and relaunch Photoshop to check if that helps. You can try to reset the preferences of Photoshop using the steps mentioned here: https://adobe.ly/2Qzc0K3

Please backup your settings prior to resetting the preferences. You can check: https://adobe.ly/2vNz6FG

Let us know how it goes!

Regards,

Thanks much for your response. I can't quite pinpoint when it started - it was either after the latest PS CC 2020 update or after the recent upgrade I did from Nik Collection 2 to 3. Both occurred around the same time. The toggling of the Legacy Composting from unchecked to checked didn't work.

Also, please try removing the Nik Collection and install it again.
