I'm experiencing this also but it's much worse than reported above, in all of these environments performance is behind 19.10/3.34:
* gnome-session / X11 * gnome-session / Wayland * ubuntu-desktop / X11 * ubuntu-desktop / Wayland ubuntu-desktop / X11 is by far the worst combination, but in all others I'm able to see windows in the overview enlarging "inch by inch" with noticeable frame dropping and stuttering. Moreover, I've tested this in Fedora 32 and up-to-date Arch. Performance in Wayland is great in both systems (but, again, there is regression in X11, which has always been bad for me anyway, it's just worse now). I've a Huawei Matebook X Pro, with Intel 620 and an NVIDIA gpu. Performance is bad using any of the graphics cards. Specifically, the problem has always been with the overview animation,the application spring is ok since 3.34. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell-extension-ubuntu-dock in Ubuntu. https://bugs.launchpad.net/bugs/1872796 Title: gnome-shell animations are noticeably stuttery when the Ubuntu extensions are enabled Status in gnome-shell package in Ubuntu: Confirmed Status in gnome-shell-extension-desktop-icons package in Ubuntu: Confirmed Status in gnome-shell-extension-ubuntu-dock package in Ubuntu: Confirmed Bug description: I have a Dell XPS 9360 with a FHD screen and a Intel HD620 iGPU, running Ubuntu 20.04. On this system animations should be smooth and at 60fps, but this is not always the case. The applications animation (the icons coming from the bottom left) is specially stuttery most of the time. Sometimes it is buttery smooth, but most of the times it is not. It is difficult to pinpoint when. Some exploration that may help to find the issue: * I also have a desktop with 20.04 and a Nvidia 750ti and it seems to be much smoother. This seems to indicate that the problem is somehow related to the Intel iGPU. * Animations seem smoother under Wayland. But, because of other limitations, I am staying on Xorg for now. * The application animation is super stuttery the first time it is opened in a session. It gets slowly better with subsequent uses, although never totally smooth. " The animation is noticeably more stuttery if it opens the “All” applications tab instead of “Frequent” apps. Maybe the number of apps (icons) is a factor? * Vanilla gnome-session seems to be smoother. Maybe the problem is related to Dash-to-dock or another Ubuntu extension? (In my ubuntu session only default extensions are enabled). These datapoints are mainly subjective as I have no means of properly measure animations performance. Don't get my wrong, 20.04 is a clear improvement over 18.04. But it seems there is some room for improvement at least in this hardware.
