Package: gnome-shell Version: 3.22.3-3 Severity: important Dear Maintainer,
Over time, window and workspace operations (e.g. switching to overview mode, switching between workspaces, switching focus from one window to another) get slower. Immediately after logging in on a freshly booted system, all these operations are very fast and smooth. After several hours, they become very slow. Switching to overview mode is particularly slow -- there is often a 2-3 second delay between the time I press the overview key and the time when the screen shows any change at all. At that point, it immediately jumps to the overview without any visible animation. When performance is slow, gnome-shell CPU usage is generally higher than when performance is good, but it's not pinned at 100%. Chrome and chromium also tend to use more CPU when performance is slow, but killing them does not improve performance of gnome-shell operations. In fact, closing all windows does not restore gnome-shell performance. The same problem happens for both gnome on X and gnome on Wayland. Restarting gnome-shell (via Alt-F2 r) does not help. Logging out does not help. Restarting gdm does not help. Rebooting restores performance. I have verified that the system is not swapping. Machine is a Dell Precision 5510 laptop. Output of lspci given below. Gnome system info states that gnome is using the Intel graphics, not the NVIDIA controller. Thanks for your help!
