Strang random behawiour of Qt application

[pedrito]

I have found a strange behawiour of my Qt Widget Application.
All works fine, but sometimes all the widgets of the GUI get a background color similar to black, as if all the
widgets have losed their style.
Is there anybody that has seen somthing similar?
Thanks

Hi,

No, never encountered that issue.

What version of Qt are you using ? On what platform ? What is your application doing ?

@pedrito Also it sounds a bit like your app is freezing - some systems darken windows of frozen applications.
Can you post a link to a screen-shot?
