@ramkiponnam can you start a new thread about the symbology rotation please.

The new 5.2 still has some rough edges it appears 🙂

I’ve confirmed the performance issue myself - didn’t notice it when testing since I usually work on smaller data sets where the performance drop wasn’t as noticable.  
I’ve also found a fix for the issue. I’m testing if nothing else is broken because of it and will commit the change soon.
