Comment 17 for bug 1763892

Hi there. Sorry but I'm a bit confused as to which branches will be getting this fix and which ones will not be. Specifically I as wondering if a fix might be back-ported to 18.04. Because I need to stay on LTS release for the canonical kernel live patching service. Otherwise I really would not mind upgrading. Not using wayland over here just xorg. Here is my mutter version. And my Ubuntu software updater says 'no new updates'...

 $ sudo apt search mutter | grep -i mutter
