Well! After a couple of sessions using Chromium with no flickering (and a long time away from the laptop I'd reported the fault from), the flickering is again evident on that same build of Budgie.

Hi Olivier, sorry for my slow reply - am writing from another machine at present. Will post the results of that test in the next day or so, but in the meantime stopped by to report the following: The other day I spent an hour in Chromium on the laptop on which I'd reported this issue, and for reasons I'm not sure of, the screen didn't flicker!

Can you share some details about your graphics card and drivers? There's a new version in the archive (65.0.3325.146-0ubuntu1), can you please upgrade and let us know if that makes a difference?
