The last few releases on 7.7 beta cycle have been laggy at best. I'm running macOS 10.12.5 and for at least the last two betas any initial attemp to scroll once I've opened a layout causes a spinning beach ball stall that can last as long as a minute. It is (for me at least) bordering on becoming unusable. On the plus side, once I get through my first spinning beach ball time out, performance seems to improve. I've attached logs if that will help.
