I am using Gnome 3 with Ubuntu 14.10 with a multi monitor setup on an nvidia card with nvidia drivers.

I experience that Windows are not (re)painted correctly. This happens in the installer as well as Netbeans IDE.
Since I did not observe this with other Java/Swing applications I assume it is a bug in the platform.

The behaviour can be observed with older versions of Gnome as well.

This problem can be forced when switching to a different virtual desktop, waiting a moment for a state change that will change the window content off-screen and switching back. It happens without switching to another screen some times as well afaik.

I will attach two sample screenshots.

Only known workaround: Resize window to force a full repaint.
This is especially annoying when waiting for a long process and not noticing if it is already finished.
