When I start AppCode first time of the day and I try to search for something using cmd + shift + F it causes the interface to hang. I have this problem with multiple projects and also tried EAP. Issues occurs in 2019.1 and 2019.2 EAP. It's not a RAM issues since that only uses 20% of total available RAM at the moment. Sometimes it help by building the project first and search after but this doesn't fix it every time.
