Comment 17 for bug 954352

Bug #725434 resulted in cairo-gl being disabled for causing "a 300% increase in memory use at login as compared to previously". Comment #12 mentioned a theory that this memory problem was actually in a version of libc nolonger used in Precise. I just tested the difference between memory use of some applications I expect to be using gtk+ at startup in Precise with and without cairo-gl enable. I installed cairo-gl via:

sudo add-apt-repository ppa:ricotz/staging
sudo apt-get install libcairo2 libcairo-gobject2

While total real + swap = virtual memory is about the same, a number of applications do have roughly 300% of the memory usage with cairo-gl enabled as they do with it disabled. So it looks like we still have the cairo-gl + Nvidia proprietary driver memory problem?
