Creative Cloud playing up; brush painting grey squares.
For some reason when using my brush on layer masks my brush paints grey squares which can't be eradicated with CtrlZ; I have tried all the fixes and nothing seems to work, I have trtied using older CPUs in preferences which eradicates the grey squares but totally destabilises various other processes.
Unless this is sorted with an update I will cancel my subscription forthwith, delete CC and use Affinity Photo 2 as my default image processor and Faststone as my image browser
FYI I am on Windows.
