Gui is not showing menu bar

Hi,

on my notebook paraview 5.4.0 (stable) for windows 64 bit is not showing the menu bar e.g. "file", "edit", "view",... Like on the picture below.

Some Details about my software/hardware:

• Paraview Version: 5.3.0 and 5.4.0 (i tried both)
• OS: Windows 10 Pro 64 bit Version 1703
• Graphics: Intel HD 520
• Graphics Driver: 21.20.16.4678 (date: 17/05/2017)

Any information missing?

I tried it also with my other notebook, same OS, but Intel HD 4000 and it works. Any idea what the problem could be? Thanks!
