ubuntulooks causes massive memory use at startup for Firefox 3 trunk build

[Martin Meyer]

Binary package hint: gtk2-engines-ubuntulooks

See this bug at Mozilla: https://bugzilla.mozilla.org/show_bug.cgi?id=367509

There seems to be some issue with the ubuntulooks engine that causes Firefox 3 trunk builds to show memory leak behavior when FF starts. When I launch a Firefox trunk build all my ram gets consumed and then my swap more slowly, then eventually all the memory usage drops off and Firefox opens. The problem goes away completely when I change my theme to clearlooks. Also, my performance in Firefox seem MUCH better with clearlooks than it did with ubuntulooks. The UI is much more responsive and Google Maps scrolls faster.

There is a backtrace for the offending thread in the Mozilla bug but I don't know how much it will help.

The issue is that Firefox tries to draw a progressbar of very small size (width=1, height=1). This results in a negative object allocation in cairo, which makes it eat all the memory.

I can confirm that I get the same problem with firefox 3 (minefield) and ubuntulooks.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with latest Ubuntu release? Thanks in advance.
