Windows content appears transparent before fully being created

[Omer Akram]

Any window that takes a while to render on screen, first appears transparent and only the window frame shows.

e.g.

Network Indicator > Edit Connections... and double click on any connection to change their settings

What happens:
The new window is created but initially with transparent content area. See attached image and video.
