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. [ Test Plan ] 1. Open Settings. 2. Move the cursor up/down over an empty area of the desktop. 3. Move the cursor up/down over the list pane on the left side of the Settings window. Expect: No difference in cursor smoothness whether the window below is animating in response to movement or not. [ Where problems could occur ] In frame scheduling, so the risk is more stuttering or screen freezes. [ Workaround ] Add this to /etc/environment: CLUTTER_PAINT=disable-dynamic-max-render-time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2023766/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
