Yes I would expect Xorg to be slightly better right now. For reasons unknown as yet, moving the mouse in a Wayland session forces the GPU to redraw everything which will slow it down and stutter more. But in Xorg sessions the mouse pointer can move freely without the GPU having to redraw anything.
I'm surprised you see a difference with lowlatency kernels, but if it works for you then great. So this is a general performance bug. Even though the system is over 10 years old I think it should be performing better, but know that gnome- shell is not yet fast enough for most machines, even new ones. I will continue working though the lists of performance problems here: https://trello.com/c/Q6JYXPPs https://trello.com/c/pe5mRmx7 and hopefully in future we will have good enough performance to close this bug. ** Summary changed: - stuttering mouse movement after any shell window opens + Stuttering mouse movement after any shell window opens, on AMD Athlon(tm) 64 X2 with Radeon HD 3450 ** Also affects: mutter (Ubuntu) Importance: Undecided Status: New ** Changed in: mutter (Ubuntu) Status: New => Triaged ** Changed in: gnome-shell (Ubuntu) Importance: Undecided => Medium ** Changed in: mutter (Ubuntu) Importance: Undecided => Medium ** Changed in: gnome-shell (Ubuntu) Status: Incomplete => Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1772271 Title: Stuttering mouse movement after any shell window opens, on AMD Athlon(tm) 64 X2 with Radeon HD 3450 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1772271/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
