Hi, since downloading AP 1.5 on my mac with OS Sierra, I have not been able to retouch live filter layers, such as gaussian blur, etc. When I create a Gaussian blur live filter layer on top of a pixel layer and I try to use the paintbrush tool to remove parts of that layer, nothing happens. I tried with other live filters (not all of them) and I get the same results. I used to be able to do that with no problems before so I know it is not a problem with my technique. Has there been a change in the properties of live filters?
