Qt Creator menu bar is missing on Lubuntu 15.10

[Kingofrd]

I've just installed Qt 5.5.1 on Lunbuntu 15.10. The main menu bar of Qt Creator is invisible, but I can click it. How do I fix this?

Most probably by contacting the maintainer of the qt-creator package for your distro... Or maybe update your graphics driver.

I'll ask this question from Ubuntu forum.
and Thanks for you reply.
