hi brett, thank you for the report (i've seen a few similar ones from other affected users as well). would you be able to come up with a more narrow regression range with a tool like https://mozilla.github.io/mozregression/ - there's a short tutorial video on its homepage, if anything is unclear please also feel free to just ask...
