FOUND THE ANSWER To get it to work as a plug in, one needs to set Luminar to run in "admin mode".

I have the "preferences" set to accept "unknown plug ins" and Skylum filters appear in the drop down menu of Filter plug ins. BUT it does not activate the plugin. Searching on the internet indicates this is possible on PC based systems (I am running a PC) but trouble with a MAC. What can I do to get it to work? I'm running Intel(R) Core(TM) i7-9700 CPU @ 3.00GHz 3.00 GHz, Windows 10 Pro, NVIDA GeForce GTX 1660 SUPER

Thanks, but as you may see, I had updated my drivers ahead of my original post. The solution that PeteMacca stated worked well. Thanks though.

PeteMacca, YES! thanks!

As I zoom or move a tool (brush, etc) over the screen there are blocks that appear. Sometimes the blocks are white, sometimes it has part of the image, and sometimes it's a pattern. I have set graphics accelerated GPU on, but no change after. While I use filters in 'Photo' I have no problem with the filter image - only after I return to Affinity Photo. I run an Nvidia GeForce GTX 1660 Super card and the onboard is Intel UHD Graphi c 630. I've already looked for updates on the GeForce driver side. It is seen on the image the white random blocks and another on the bottom having part of the image itself. There is no pattern to them.
