random autocompletion hangs are back, intellij hangs for a minute or two before autocompletion pops up. Unfortunately it is not reliably reproducible sometimes it happens, sometimes it doesn't.
Also when opening a kotlin file, its highlighting is very basic (only reserved words and strings), after 30-40 seconds full highlighting appears.
