I am on Debian Buster amd64 with gnome-shell 3.30.1-2. I just did some updates and noticed that I now have this crosshair pattern on the desktop/background. Does anyone know why this pattern, seen below, has appeared?
- Testing featured that was left enabled?
- New window organization hint?
- Weird plugin on my part?
Thanks!
EDIT: Looks like the default background itself has a cross on it.
