Qtvirtualkeyboard gives black screen when automatically hiding of the windows taskbar is enabled

[Yina]

Hello,

When the option of "automatically hide the taskbar in desktop mode" of windows is enabled and you open the QtVirtualKeyboard the window becomes entirly black so you can't see what you're typing anymore. The typing still works there is just a black overlay over the entire screen.
When this option is disabled the keyboard works as it should.
Is there a way to fix this problem?

Kind regards
Yina
