P: Alt+drag layer mask - Copies but layer icon does not update

To copy a layer mask to another layer in the layer panel i use the method: ALT+drag to the new layer mask icon in the layer panel.

In Photoshop 24.6 the mask is copied and takes effect - but the icon does not update. I have to click on the eye icon of the new layer Layermask icon.... only then the correct display is updated.

Of course I have tried the usual measures:

• Complete uninstall (with preferences)
• Reinstall Photoshop
• Deactivating GPU in preferences and using GPU better acceleration without OpenCL.

Nothing helps

Then I noticed that everything works correctly in PS 23.5.5. But in all 24 versions I have the described error. So the cause must be a bug in PS 24.x. Or did I miss something?

Kind regards, Kai
