I have a very annoying problem with photoshop and it's happening very random.
As you can see in the video, after 1:28, when I add an anchor point, nothing happens. Somehow the photo is stuck. If I do something, nothing happens, at 1:34 I'm zooming out, at 1:42 image to greyscale. Nothing is happening with the photo, but you can see in the History, the photo is in greyscale. The only thing I can do with the photo is saving it (luckily).
The screens doesn't refresh if I make it a floating window. And it's only specific for 1 photo. If I have opened multiple photo's and the canvas stops updating with a photo I'm working on, the other photo's don't have that problem.
Sometimes it happens after 7 actions and then after maybe 30 actions or more. This morning it happened already 4 times in 5 minutes and one time after 3 second. I opened a photo and only used zoom and the hand tool.
I already uninstalled photoshop en reinstalled it again, but the problem is still there.
We're sorry to hear about the issue you are facing in Photoshop 2021 with the canvas not updating as you work. Would you mind telling us the exact version of Photoshop you are using? Since when are you facing this issue? Did this start after a update update?
Also, just to clarify, this is happening with any image you working on & not a specific image (the one you have showed in the video), right?
If you are experiencing this behavior with multiple images randomly, then try disabling the option to Use Graphics Processor from Photoshop by going to Preferences, then Performance. Once done, quit & relaunch Photoshop to check if that helps.
If the issue persists, you can try to reset the preferences of Photoshop using the steps mentioned here: https://adobe.ly/2Qzc0K3
This is happening very random and with any image. Sometimes after 5 actions, sometimes after 30 action and sometimes it doesn't happens at all. And if I have opened multiple photo's, the issue is only with the photo I'm working on.
I'm having this issue maybe a year, I think. I already had it in version 21. This morning I updated photshop to version 22.4.2 and after a few minutes it happend again.
I've now disabled Graphic Processor in the Preferences and will try this for now.
And if this does not work, I''ll reset the preferences.
