Public bug reported:

I've previously reported this bug for Ubuntu 17.10 and firefox and even
thunderbird are still doing what they did during the development and
eventual release of 17.10. this is annoying. It still creates the heavy
pixelation, scrambling, juttery screens when opening and during times
when i'm resizing windows and/or have other windows open that come from
firefox such as download dialogue window that the operating system is
presenting me with options about my downloads (open or save options) i
get this quick, black box to form around the window and disappear when I
click certain option boxes in those windows. I've tried this with
Chromium and nothing ever happens with that browser and I've had other
system windows open such as my file manager program and some other
programs running and tried everything to create the effects i see and
nothing. it only comes from mozilla products (firefox and thunderbird).
and even the tor version of firefox has the odd black box around it when
i resize it as well. it all seems to be just focused on firefox,
thunderbird and the tor firefox browser.
