Qt Creator Crashes Ubuntu 18.04

I am having reproducible case where on second start of Qt Creator entire desktop gets messed up. Here is my setup.

I am running on Mac OS X Mojave with latest Parallels 14. I installed (guest) Ubuntu 18.04 Desktop with all latest updates as of today (Oct 29 2018). Next I installed Qt 5.11.2 with Qt Creator 4.7.1. Now the problem is that on every SECOND start of Qt Creator entire desktop bets mess-up. 

1. Start Qt Creator (no need to open project, but opening does not change anything)
2. Quit Qt Creator 
3. Start Qt Creator again 
4. Desktop is unusable

Also noticed (pointer in red arrow) that CPU is at 100%

Also clicking on any visible desktop icons I can't open anything. Also desktop background is gone.

Perhaps this is problem with Parallels (Parallels tools installed), Another 16.04 works just fine

I also notified Parallels and submitted "Send Technical Data" 

A technical report with the ID number 282192457 has been sent to Parallels.
