Comment 9 for bug 491869

I am not sure, whether I am doing it correctly, I just extracted the .tar.gz into ~/.themes.
The file I downloaded is named newwave-090-beta-1.tar.gz
The theme gtkrc file inside reads: Version: 0.9.0 Beta 1 [23/04/2010]

After doing that I reselected the theme from the Appearance manager.

The lock screen buttons now have similar sizes, so nice one on that.

However I noticed something awkward, that may or may not be connected to my installation procedure: when the screen is locked the background is not complete black any more, but rather contains a poor quality black-and-grey pattern, resembling low jpeg quality compression. The same pattern is found as the background on some widgets like the Thunderbird and Firefox tab-bar and status-bar, and the Appearance Manager's background too.
Or is that an intended part of the theme?
