P: Select and Mask Workspace preview selection tools

This was the reply I got on the Adobe forums

We're sorry about the trouble with Select and Mask in Photoshop 22.4.1. Would you mind confirming if you are talking about the live preview not working while using Select & Mask? If yes, this is a known issue with Photoshop 22.4 & 22.4.1 & our product team is working on a fix. For some users resetting the preferences has helped. If that didn't help in your case, you can roll back to the previous version of Photoshop using the steps suggested here: https://adobe.ly/2wH0JjE

Please uninstall the latest version of Photoshop first & select the option to Keep Preferences prior to installing the previous version.

This has been aknowledged as an issue...there is a bigger thread already active ( i know ive got the same problem!)

Just chiming in...same issue for me on 22.4.1 on Windows. Been battling it with for days....resetting preferences etc. So frustrating.

posts on the Adobe forums ( and a reply from employee) led me here.

Any ETA on the fix

"Select and Mask..." previews no longer working correctly for me from the View pull down, any changes not previewed in some modes. For instance: "Overlay" will preview changes, on black or white won't, Black & White does, On layers won't. I use these all the time and they suddenly stopped working even after multiple restarts. Currently in these non-working modes, the preview remains static, only showing the current layer's mask, no matter what changes I make to the sliders, while for several of them, the preview works as expected.

@Wilson have you tried using previous versions? Im using 22.2 and for Select and Mask that works well  

@dramenon That doesn't work. What else can I do to be able to use the Select and Mask properly again?

i went back to 22.0.0 and it works now

i went back to 22.0.0 as the one 22.3.x still didn't work for some reason.  at 22.0.0  it's working for me now.  i'll just wait for the next update.

Same problem, mask "real-time refinement" disabled. Win 10.

The native canvas workaround did help. Thanks!

i only see something happening when using the black and white view mode.

of course i can not work this way.

really how long until adobe hires someone who actually knows how to code GPU acceleration?

every new version something with GPU support is broken. liquify, select and mask or some other stuff.

no other graphic software i use has so many GPU issues.

and adobe is 2D stuff, simple pixel manipulation compared to other software.

i run 3D software that does way more in terms of GPU processing and runs fine with OpenCL and Cuda.

get your stuff together.....
