I (finally) managed to find one of the sources for this problem. It looks like our "sotware-center.css" file causes some css that has a memory leak to be drawn.
To reproduce: - open a tool like htop and sort by memory usage - run software-center and scroll around the lobby - watch the htop RES column for software-center increase just from scrolling Note that this does not increase any python visible object count, just the RES data. When the software-center.css is disabled this stops leaking memory. I will try to build a stock Gtk test case next. ** Changed in: software-center (Ubuntu) Status: New => Confirmed ** Changed in: software-center (Ubuntu) Importance: Low => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1058523 Title: Software center page changes add between 2 and 6 meg to the memory size To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-center/+bug/1058523/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
