Bug Description

> What you expected to happen

Normal operation: no delays when typing or moving windows around

> What happened instead

Since a few days ago I started noticing occasional lag when typing (sometimes three words appearing together, as on a slow netword connection) and when moving windows, as if the system was on a high load. If I close almost everything it gets a little better, if I restart Gnome Shell with ALT-F2 r RETURN it gets better for a few minutes.

Ghome Shell is always one of the top consumers of CPU and RAM, but this was always the case. I don't have particular problems with RAM, I'm usually not using more than 20 GB out of 32 with many long running programs (VMs, browsers, etc).

Sometimes I notice a Gnome Shell crash in the logs, as the one I attached.

Thanks for the bug report.

Please start by uninstalling all of these extensions and then reboot:

Hi Daniel, I did that a few days ago. The extension that triggers the problem is gsconnect. There is a related open bug on that extension at https://github.com/GSConnect/gnome-shell-extension-gsconnect/issues/1028

I waited to report it here because we were doing some investigations then I forgot. My bad.

It could be a problem completely due to the extension or split between the extension and the shell. I don't know how to help investing it.
