Anyone else having frequent brief IDE freezes even with 2021.1? Unfortunately they’re not long enough to trigger an error report. Reformat code: several seconds (esp. annoying when auto-formatting on save) Copy file: several seconds Autocomplete suggestions: up to 2 seconds But the sheer amount of the mini freezes is really annoying.
It’s probably caused by having a large amount of DSL/closures which is quite typical in Kotlin/React projects.

Can you please record a CPU snapshot ( and file a YouTrack issue with some description of actions.

Two years passed and my IDE still freezes hundreds of times a day for anywhere between 1 and 30 seconds… When is Fleet ready?

I think what you really want is the new kotlin plugin based on k2. intellij idea core is super snappy.

Do you mean actual freezes or the annoying macOS flickering? The latter is finally fixed with 2023.1 EAP 5.

Freezes. k2 might help too, indeed.
