Invisible buttons, ...sometimes

[Gregor Mi]

Hi there,

I encounter a problem with invisible buttons.

My dev env: running Plasma 4 on openSUSE 13.1, KDE version 4.11.5
and I use latest frameworks build from today (2014-11-02)

When I start for example

$ kcmshell5 mouse
or
$ ksnapshot

all the buttons are missing... sometimes. If I restart the applications
it switches between "buttons visible" and "not visible" in a random
fashion. Buttons are still clickable if you know where they are.

Here are 4 screenshots:

Any idea what might causing this?

Regards

Gregor
