Based on our logs, you are indeed running a screen size and/or scale that is problematic for the current version of charts. As mentioned, we already have a bug filed internally to investigate this!
In the meantime, you can zoom out the interface a bit ( Ctrl + - ). That should fix the issue temporarily - the key is to give the map a bit more space to breathe.
I have added a reference to this topic to our bug, so we’ll let you know when we get this fixed!
Apologies for the inconvenience.
Kind Regards,
Malte
