The problem is that some Qt UI elements (menu items, dialogs, ...) are rendered blank in black (randomly) - check the screenshot below:
I'm on Ubuntu 16.04.5 with Docker 18.06 and Qt 5.01.
But... why? Why docker?
Anyway. Do other applications show normally? Like some standard Gnome/KDE apps.
I strongly recommend using something newer than Qt 5.0.1. It was an extremely buggy release. And it's super old.

I have the same with Ubuntu 16.04 on Docker and Qt Creator 4.5.2
Nothing we can do about it. Its a docker issue.
Make sure you run a full Linux with X server etc inside the docker.
Then i had no issues running my app.
If you use a special docker, it might have side effects as not operating like a normal OS would.

Geeva, was this ever solved?
I get the same problem with Qt 5.9.5, Ubuntu 18.04.6, GCC 7.5.0, Docker 20.10.14
