Refine Edge tool still broken
since version 2015.5 the refine edge tool (which is now part of the 'select and mask' window) doesn't work, it unselects areas and adds transparency.
this bug occurred in version 2015.5 (with the new 'select and mask' tool) and since then, 2015.5.1 and the new 2017, haven't been resolved.
nothing seems to work. I tried to update my Nvidia card (GTX970), deselect 'Use Graphcis Processor', delete config file, uninstall and re-install photoshop - nothing helped (just to be clear, I don't have custom brushes / presets /actions in Photoshop).
I tried the help center (live chat) three times, each time they said its a known issue and it will be fixed 'in the next update'. well, Photoshop updated twice (2015.5.1, 2017), but this tool is still broken. I cant get any work done.
any advice?
