Sometimes windows, dialogs (gnome, KDE) go black and only the decoration as the titlebar remains and its buttons work as well. It happens a few times a within 10 hours continuously working. More or less twice a hour.
here the setup:
- tripple monitor, NVIDIA default driver
- Ubuntu latest LTS (14.010), x64 with no tweaks or mods/other window-manager installed. All on default, just Oracle-Java instead of OpenJDK.

other notices:
It comes with multiple Java-Applications (PHP/Webstorm, Eclipse) and seems to affect other applications as well: Chrome, Krusader and also gnome dialogs or any other gnonme based applications.
Keyboard goes off in Java applications, no idea this is related but it happens the same rate as the window problem.
- it came with the 14.4 update
current solution:
- press escape to close dialog or application (crucial sometimes) and redo the step.
As I don't have anything special installed I'd love to know what to do about, its sometimes more frequent and really annoying.
