This doesn't seems something easy to understand, because `org.gnome.Shell.Extensions` could be loading *ANY* kind of javascript code that is imported from gnome extensions.
Some of this code is definitely setting a wrong pango text, and gjs thus doesn't free it properly. It could be also an issue due to wrong JS-string -> C-string mapping in gjs but it's very hard to reproduce for me. ** Description changed: + Some JS traces I see are: + + + Jul 14 18:52:30 zerocool gjs[114030]: Attempting to run a JS callback during garbage collection.
