The issue seems to be some form of incompatibility between being zoomed in when using Chrome and saving views (no I don't understand why that would be either!), I noticed the issue originally when I was doing some training so my screen was quite zoomed in. I've been able to resolve it by re-setting my zoom back to 100%.
We raised a case with MS about this and have received the following:
"This issue has been recognized centrally, a fix has been developed and updates scheduled. For your region [Europe] the fix is tentatively planned to start rolling out on 12th December 2022"
