Qt5Core.dll errors in Win10 logs when exiting R15

I have noticed that when closing Resolve Studio 15, the mouse spins for a few seconds. This did not happen in Resolve Studio 14. No error is displayed but the Windows 10 application log records the errors below. I have not experienced a crash of any type although my projects are very small.
