This might be related to a triple buffering issue: https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1441#note_1679803
If it is caused by triple buffering then you will find the issue is temporarily fixed in mutter 44~rc (which lacks triple buffering), and will return later in 44.0. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/2009687 Title: [lunar] Nvidia GPU unused but still powered Status in GNOME Shell: Unknown Status in The Ubuntu Power Consumption Project: Triaged Status in gnome-shell package in Ubuntu: Triaged Bug description: Hi, Lenovo Legion 5 16" i7 12700H RTX 3070 Ti Nvidia 525 proprietary driver (official Ubuntu packages) Nvidia on-demand mode Ubuntu Wayland or Xorg sessions Ubuntu Lunar up to date I noticed a high power usage using powertop (or simply remaining time in g-c-c...).
