Most of the time i open 3 project. After a while (15min-2 hours) the Appcode becomes very slow and just loading periodically. I mean every 5 sec. I work on a 27"late 2015 imac with 16 GB RAM. A noticed it with ver 2017.2.2 and the previous one as well. I checked the memory consumption, its "only" 2.5 GB.
