Bug Description

[Test Case]
Performance fix - only way of testing is performing the benchmarking steps again to check if there is improvement.

[Regression Potential]
Redraw/refresh problems.

Original description:

I'm finding my development Unity sometimes pauses (stops responding for a little while). When this happens I notice its DrawList has spiked to several thousand.

Hello Daniel, 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!

This fix can not be verified except with the new Unity code coming in 5.16:
https://code.launchpad.net/~thumper/unity/regional-damage-sru/+merge/116796

Only that code exploits this bug.

Ok, then, for now, we can set this to verification-done and then reopen it/leave it closed once the new unity version with regional damage (?) is out.

removed: verification-needed

The verification of this Stable Release Update has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.
