ADDITIONAL INFORMATION
Tested on 3 different Win10 PC's with: Intel graphics 550, Nvidia 1060, Intel Graphics. Tested with Kdenlive 19.04.2-5 (QT 5.12.4) 19.04.2-4 (QT 5.12.3) and 19.04.0-2 (QT 5.12.2). With all 3 versions the GUI issue appears with Intel Graphic 550 only. Downgrading the driver to x.6709 solves the issue.
When exit Kdenlive:
Intel graphic driver newer then x.6709: Dbus-daemon.exe and "host for console window" stays within Kdenlive 
The 2 other PC's shows the Dbus-daemon.exe only 
After downgrading the Intel graphic card 550 to x.6709 the Dbus-daemon.exe shows "normal" again .
