Hello Łukasz, or anyone else affected,

Accepted nux into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/nux/2.14.0-0ubuntu1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from verification-needed to verification-done. If it does not, change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

    - QueueDraw is very expensive (LP: #994884)
    - Unity is slow and pausing occasionally (when its DrawList size spikes,
      to almost 6000!) (LP: #1014610)
    - Conditional jump or move depends on uninitialised value(s)
      nux::GraphicsDisplay::ProcessXEvent(_XEvent, bool)
