Package: gnome-shell Version: 3.38.4-1 Severity: normal Dear Maintainer,
When switching to an application on a different workspace by clicking on the icon in the dashboard, some error messages appear in the journal (see below). Moreover, there is a rather unpleasant visual glitch: instead of a smooth animation, the background is showed briefly and abruptly. The bug is present in both Wayland and Xorg sessions with no extensions running. The problem seems to be in the interaction between the C and the JavaScript code in gnome shell. It is easy to reproduce as it happens every time: 1. Launch two different applications and put them on different workspaces. 2. Switch between them by clicking on the icons in the overview. This bug has also been reported upstream here: https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/3341 Thank you for maintaining this package. Best wishes, Todor Relevant excerpt from the journal: ---- Object .Gjs_ui_workspace_Workspace (0x562acc6c07a0), has been already deallocated — impossible to set any property on it.
