Verified fixed on jammy in 42.9-0ubuntu2. Tested using the test plan at the top of the page and also a 1000Hz Microsoft Classic IntelliMouse. I actually don't think the bug was as visible in 42.x as it was in 44.x. The reason is likely because triple buffering in 42.x didn't rely on the problematic dynamic-max-render-time feature as much as newer releases do.

> On test plans, I see both this bug and the other one will be individually > tested, > but what's the plan to ensure that other behaviour in mutter isn't regressed? Mutter and GNOME Shell are massive projects so the next bug is always somewhere you don't expect. I would not recommend focussing permanent test plans on any regressions that were found in 2023. Specifically addressing each one: Bug 2026887: Caused by a narrow hardware/kernel combination. No more important than any other CPU model or kernel release. Bug 2023759: Caused by a lack of testing remote desktop (upstream too). This could obviously be better tested but I argue the feature is too obscure to be a top-level test case we ask anyone to do on every update. Bug 2023363: Caused by 16 milliseconds being too small a difference for most to notice. Bug 2023766: Microstutters of a few milliseconds were a regression in 41.0 and went mostly unnoticed by everyone for several years because of how minor it is. Bug 2017097: Caused by a combination of being too hard to notice for people who did test Raspi, and me being only one person too busy dealing with a rewrite of triple buffering caused by a last-minute upstream API redesign in 44.0. Bug 2017137: Caused by a combination of being too hard to notice for people who did test Xorg, and me being only one person too busy dealing with a rewrite of triple buffering caused by a last-minute upstream API redesign in 44.0. To find future regressions more effectively we need both more people testing proposed for longer, and more hardware/software combinations. Perhaps slower phasing too since such obscure bugs are so easy to miss by most people. This isn't just a mutter issue. Almost every day I track obscure bugs back to the kernel caused by hardware combinations we simply can't expect to get tested exhaustively before every release. -- 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/2023766 Title: Mouse cursor stutters over GUI elements that are animated Status in mutter package in Ubuntu: Fix Released Status in mutter source package in Jammy: Fix Committed Status in mutter source package in Lunar: Fix Committed Status in mutter source package in Mantic: Fix Released Bug description: [ Impact ] Mouse cursor stutters over GUI elements that are animated, such as GTK apps, web pages and shell elements.

I don't have a good answer to that, sorry. Mutter and GNOME Shell are very large projects and the desktop team only has between 1 and 3 people working on them at any given time.
