Description Olli Pettay [:smaug] 2012-10-17 15:05:35 PDT
Something keeps WebGLTexture alive and that ends up keeping
the whole document alive.
Comment 1 Olli Pettay [:smaug] 2012-10-17 15:07:35 PDT
The addon from Bug 726346 can be useful for debugging (restart after installation).
After running cycle collector (maybe couple of times), "Find documents" shouldn't find any documents.

This is very possibly bug 795186: let's fix that first and see if this bug persists.
Comment 3 Benoit Jacob [:bjacob] (mostly away) 2012-10-23 09:27:33 PDT
This is fixed by , in my limited testing which consists in loading Nokia Maps, opening a new tab with about:memory, closing the Nokia Maps tab, and clicking GC and CC (but NOT 'minimize memory usage') a few times in about:memory and verifying that all webgl metrics disappear.
Comment 4 Benoit Jacob [:bjacob] (mostly away) 2012-10-24 07:25:36 PDT
This seems to have been a regression from the port to WebIDL bindings as well --- just tested a nightly build from Sept. 17 and it didn't have the issue.
