Hi there, @ZoeJones ...
Thank you for confirming that you've tried different web browsers ... that's one of the things I would have suggested. I would also suggest clearing your browser's cache/history files. Once you do that, close your browser, re-start it, and then log in to Canvas again to see if things look better.
Another thing to do is to contact Rose State College's Online Learning / eLearning / Distance Learning department. They might have some suggestions for you. I browsed their website, and I found this page for you: Canvas (rose.edu).
Finally, I would suggest you contact the Canvas Help Desk staff. They may also have some suggestions for you. Check out this Guide for more details: How do I contact Canvas Support? - Instructure Community
I hope this helps! Sing out if you have any other questions about this...thanks!
