This is definitely looking like a bug, IMHO.  The problem is noticeable on my Win 10 4K Desktop.  I do not see the problem on my Win 10 notebook.

On my desktop:

If I use PS CC 2018, 19.1.6, select and mask -> refine edge, modify mask, etc works normally.

If I use PC cc 2019, refine edge, modify mask does not work correctly. The best way I an describe is is as follows:


  • On a layer, I make a selection using any of the selection tools such as lasso, brush, select subject etc.
  • I then click on select and mask to refine the mask and edge
  • In the select and mask tool screen, I can view the mask in the little thumbnails from the view drop down on the right
  • If I try to refine the mask, add or subtract from the mask, the larger primary screen showing the mask and the mouse movement does not reflect a change to the mask. I do see the “lasso” or brush movement, albeit no change registers in the primary screen. However, I can see the change to the mask in the little thumbnail view drop downs on the right.
  • When I close the select and mask refinement tool, the mask returned to the active layer does reflect changes.
So, in a nutshell, it looks like a glitch in the update of the primary screen in the refine edge tool.
I mentioned that it worked on my notebook. My desktop has a 4K display and dedicated NVIDIA GTX 1050 Ti video card. The graphics driver is current. Win 10 patches are also up to date.

I welcome ideas and suggestions.
