Bug 136142

Works fine here (SVN just pre 3.5.5 on freebsd)

I've been able to reproduce this with xclock, but not with anything else. What other apps show this behaviour?

I ran into this problem when I was using GLUT, and created a very small window.

But, here's a Qt example:

#include <qapplication.h>
#include <qpushbutton.h>

int main( int argc, char **argv )
{
    QApplication a( argc, argv );

    QPushButton hello( "Hello", 0 );
    hello.resize( 70, 30 );

    a.setMainWidget( &hello );
    hello.show();
    return a.exec();
}

Same problem.
Now try this, though:

#include <qapplication.h>
#include <qpushbutton.h>
#include <qvbox.h>

int main( int argc, char **argv )
{
    QApplication a( argc, argv );

    QVBox box;
    box.resize( 70, 60 );

    QPushButton hello1( "Hello1", &box );
    QPushButton hello2( "Hello2", &box );

    a.setMainWidget( &box );
    box.show();

    return a.exec();
}

You can take a screenshot of the whole window and the second button - but not the first button!

So it seems that the first widget is causing problems... And in the first example and in xclock, there is only one widget. Well, I actually have no idea how widgets and X work, so it's just a guess.

Another example.

1. Add a new panel (right-click on the main panel, or whatever; Panel Menu->Add New Panel->Panel).
2. Move it to the left of the screen.
3. Take a screenshot of it. Doesn't work!

4. Right-click, "Configure Panel...", make it shorter than 100%. An arrow appears at the bottom. (Though now you can make it 100% again - the arrow stays. Bug?)
5. Take a screenshot of the panel. It works now!
6. Take a screenshot of the arrow... Doesn't work.

i can reproduce #4 but all the rest work just fine here with 3.5.6 on Kubuntu Edgy
