Gnome Shell performance (stutter | latency | CPU):
-
Landed upstream: cogl-winsys-glx: Fix frame notification race/leak
-
Most of the week spent working on Chris’ high CPU/memory bug which is also a performance issue. See below 
Bluetooth:
- The new gnome-bluetooth 3.32.1 release (thanks Seb) has started fixing pairing bugs. Here’s the first one.
Release bugs:
-
gnome-shell high memory and CPU usage when desktop files are constantly created or deleted (formerly known as “Chris’ Nvidia bug”):
-
Produced some differential profiling and reported the results upstream.
-
Prototyped several attempts at fixing the leaks and/or just throttling
gnome-shell-extension-desktop-icons. None work sufficiently yet, but I am also still learning about concurrency in JavaScript… -
Found a related bug in glib2.0 file monitoring, and spent over a day trying to fix that. But eventually decided it was a waste of time since there are still other ways to DoS
gnome-shellviaextension-desktop-iconswhich are themselves not bugs in glib. -
Expecting to have it fixed this week.

Bad news (consistently growing backlogs): ubiquity
