I've done both a couple of times. System is fully updated, Using 5.15.3 from build repo, rebooted twice so far.
Tried Kmail, Kontact, Kmymoney, Falkon, akonadi-contacts, akregator and no noticeable problems. Will try digikam later.
Edit: Marble and Digikam appear to be working OK. emailed photos direct from digikam through kmail.
Edit.2. Not working on another PC updated and including a full update from build repo.
