After doing a bunch of edits, photoflow suddenly keeps caching, cpu goes high, and, apparently, I can’t do anything more (although all I need is export a jpg).
I end the process and restart PF, and after some seconds caching begins, the same resource intensive pattern and, again, nothing happens if I try to export.
I suspect it has something to do with the last edit, a new Shadows/Highlights layer (the only one in the set), because before that everything was going well.
