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.
  • lshw -C display: PCI (sysfs)

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.

ps: there is a duplicate about but not well described or supported: https://askubuntu.com/questions/553293/windows-sometimes-go-black

  • What graphics and drivers do you have? (you can use lshw -C display and edit it into your question)

It might be this bug in compiz. As far as I am aware of the current daily image of 15.04 should have this fixed. You could try that and see whether that helps.

  • Unity uses compiz, but Gnome and KDE use other window managers...
