Qt Virtual Keyboard's strange transparency under Debian


I'm testing the Qt Virtual keyboard 5.7.

After building and deployment, the keyboard works properly. The only
problem is that the keyboard panel's background is transparent under my
debian system(GNOME,KDE, ... tested with all the desktops). If the
background before the keyboard pops up was dark, then we can see the
keys on the dark background, but if the background was white, we can see
nothing but the buttons are still there and can be operated.

I also tested it under ubuntu, no such problem occurs.
And all my other Qt applications has no such problem.
