Actually I don't think this is unique to 560: > 2. nvidia-560 spends way too much of gnome-shell's real time (60%) inside gbm_surface_lock_front_buffer (called by lock_front_buffer).
It looks like 550 was doing the same. But gnome-shell on nvidia-550 did consistently profile differently to 560. In nvidia-550 20-25% of the main loop wakeups went to repaints. In nvidia-560 around 5% of main loop wakeups went to repaints. So it sounds like 560 is somehow spinning the main loop too much. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers-560 in Ubuntu. https://bugs.launchpad.net/bugs/2081140 Title: [regression] Poor performance in Nvidia-560 Wayland sessions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2081140/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
