My system: MacBook Pro 2015, 2.8 GHz Intel Core i7, 16GB, 10.14.6 Mojave.
I am working with PhotoLab 4.3 and Nik Collection. 3 days ago I have upgraded from Version 3.3 to 4.
After working a lot with CEP yesterday, I wanted to use SEP today. Unfortunately, this is impossible, SEP is unusable. Each correction takes several seconds until it becomes visible. There is no idea of fluent working, SEP is a complete and utter disaster now, I am totally pissed off.
