Photoshop not updating brushstrokes on duplicated window

[Stockholm-17]

Hi,

I work on a mac Studio, and I have the latest photoshop version installed. OS is also up to date.

I use to work with duplicated windows to see in real time the result of a brush-stroke while I work in a small zoomed area. This is a standard operation that never gave me issue.

The issue is that it is lagging, or just not updating the twin-window at all. I have to go to the twin-window and click somewhere. Then it does the visual update.

I made a screenrecording showing the issue: https://youtu.be/wgefV5WGcrM

Anyone with the same issue? Or is there a way to solve this?

Thank you

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.

thank you, it was confusing indeed. I try the link you provided.

What are the image’s pixel dimensions? 

Does turning off »Use Graphics Processor« in the Performance Preferences (Photoshop > Preferences > Performance > Graphic Processor Settings) and restarting Photoshop have any bearing on the issue?
