[Desktop-packages] [Bug 2052913] Re: Large Performance Regression in fullscreen windows from Ubuntu Jammy to Ubuntu Noble
Status changed to 'Confirmed' because the bug affects multiple users. ** Changed in: mutter (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2052913 Title: Large Performance Regression in fullscreen windows from Ubuntu Jammy to Ubuntu Noble Status in Mutter: New Status in mutter package in Ubuntu: Confirmed Bug description: Test system: ARM64 Ubuntu Jammy (gnome-shell 42.9-0ubuntu2) and Ubuntu Noble (gnome-shell 45.3-1ubuntu1) Default Ubuntu GNOME desktop environment used with no user added extensions. GPU driverstack identical between the two distros (eliminated as a variable). Linux kernel identical between distros (eliminated as a variable) CPU, GPU, and RAM clocks pinned to max. Test case: Minecraft Java Edition (shared drive with identical setup between Ubuntu versions). Fullscreen 1080p. Xorg display server. FPS (uncapped): Ubuntu Jammy: 177fps Ubuntu Noble: 140fps Observations: Ubuntu Jammy: gnome-shell process cpu% when camera is still: 0-1% gnome-shell process cpu% when camera is moving: 10-20% Memory Bandwidth (CPU and GPU shared): 40% Ubuntu Noble: gnome-shell process cpu% when camera is still: 20-55% gnome-shell process cpu% when camera is moving: 30-55% Memory Bandwidth (CPU and GPU shared): 50% In both cases GPU utilization is observed to be near 100%. So in summary, large performance regression regression which appears to be due to gnome-shell. There is nearly no gnome-shell cpu% usage on ubuntu jammy when there the camera is still (even with a fps graph drawn onscreen) in stark contrast to ubuntu noble.
