Aug 11 18:56:34 PIQLT501.physiq.zone gnome-shell[2714]: Some code accessed the property 'ENABLED_EXTENSIONS_KEY' on the module 'extensionSystem'. That property was defined with 'let' or 'const' inside the module. This was previously supported, but is not correct according to the ES6 standard. Any symbols to be exported from a module must be defined with 'var'. The property access will work as previously for the time being, but please fix your code anyway.

I do appreciate the extension as I like to see my screensavers running (xscreensaver rocks, what is wrong with Gnome just FORCING blank monitors on us?!), but it doesn't seem to be working anymore...

Could you tell me the GNOME version you use?
