Seeing the code, I think that the problem is that `_onEnabledExtensionsChanged()` is called both when the list of enabled extensions change, and when the list of disabled extensions change. The problem is that it is an async function, and the call in the callback doesn't wait it to finish, so it can result in a race condition. Specifically, it calls asynchronously to `_callExtensionEnable()`, which I think is what can result in the problem.
I think that this patch should fix the problem (and also fix other async calls being done synchronously), but have no way of testing it... ** Patch added: "fix-double-call.patch" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2098102/+attachment/5857419/+files/fix-double-call.patch -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/2098102 Title: Desktop switching shows windows from previous desktop Status in gnome-shell package in Ubuntu: Won't Fix Status in gnome-shell-extension-desktop-icons-ng package in Ubuntu: In Progress Bug description: When I switch to another virtual desktop using Ctrl-Alt-[Left,Right], the windows from my previous desktop remain there and are still visible as if they were part of the desktop background. In front of them, I can see my actual windows from the desktop that I'm visiting currently. Desktop icons overlap the windows in the background. I can't interact with the windows in the background but their content is updated live as the applications are running. Switching desktops using the Activities overview works correctly as expected without this issue.
