Month Cell Border Bug in latest version?

Hello, I am having an issue with the calendar, where the month views borders are not aligned.

What could be the cause of this?

 
 

Hi,
can you please tell me what browser, OS, and page zoom level do you use?

I’m looking at our default samples, and in both cases, the Month view looks ok:

so there must be something that could help me to reproduce the issue
