Context menu rendering for Java method taking too long

I recently changed machines which included a fresh install of IntelliJ IDEA 2019.2.3.  I've noticed, since the migration, that, for my larger Java projects, rendering the context menu on a Java method declaration takes a long time -- I've timed as much as 30 seconds.  Smaller projects are taking a much shorter period of time.  (Upgrading to 2019.2.4 didn't improve things.)

Such a long render time for the context menu makes that capability less than useful.  Anyone have any suggestions about how I can find out where the time is being spent so I can make an attempt at configuring around the problem?
