I noticed this happen with rounded corners on buttons a few weeks ago, also with Outlook. At the time, I didn't care about it enough to open a case with support. Sounds like this might be affecting a number of people.
I would recommend reaching out to support about it to ensure that Cvent knows that it's happening. Let me know if you learn anything about this, I'd love to know.
