Hi everyone, below you will find the updates from the Desktop team from the last week.

If you’re interested in discussing a topic please start a thread in the Desktop area of the Community Hub (this site).
We also have our weekly meeting on IRC. We meet on Tuesday at 13:30 UTC in #ubuntu-desktop on Freenode. There will be an “Any Other Business” section at the end where you are welcome to raise topics. These topics might be discussed during the meeting, or afterwards depending on the time, depth of conversation, topic and so on.

Last week’s notes are here: Monday 17th December 2018

Gnome Shell performance (stutter | latency | CPU):

• The Ubuntu Dock CPU performance fix has now landed upstream. This shaves off a third of gnome-shell’s CPU usage for maximized windows.
  • It also landed in Ubuntu 19.04 this week.
• Revised, fixed conflicts and retested:
  • clutter: Fix offscreen-effect painting of clones
  • clutter: Deliver events sooner when possible
    • Also fixed an interesting application performance bug revealed by this branch (but preexisting in mutter).
  • renderer-native: Reference count front buffers
• Divided last week’s dual throttling fixes branch into two more independent ones:
  • A minor addition to the existing “renderer-native: Accept frames without ever blocking”.
  • A new proposal: Consolidate all frame throttling into clutter-stage-cogl, which is about my 100th attempt at redesigning mutter’s frame timing logic. But this is the first design I’ve felt truly happy with, and it fixes a bug too.
• Finally returned to the erratic master clock bug:
  • Made a new attempt at fixing it, with the aim of fixing related issues like mutter#406. But the complexity and risk quickly got out of control. Plus that bug is now fixed elegantly in mutter!363 instead.
  • (TODO a smaller attempt localised to the master clock source. Not a major priority so didn’t get to it this week/year.)

Gnome Shell other fixes:

• Revised, fixed conflicts and retested:
  • backends/stage: Align the software cursor to pixel boundaries
• Added a minor build config fix

Nvidia EGLStreams/EGLDevice support:

• Just FYI, it’s still stuck in the upload queue.

Bug management:

• Backlogs progress:
  • Good news (falling backlogs): gnome-control-center, gnome-terminal
  • Bad news (consistently growing backlogs): ubiquity
