This is how it appears in Chrome on my Mac. Given that no one else on the forum has reported this yet on the forum, I’m going to guess that it’s possibly an issue with an outdated version of Chrome or something with your computer. Is the display okay in the light mode?
Only thing I can even remotely think of is when some users reported issues with their BBM displays. This is that link to their solution: Beatbuddy Screen Resolution Problems - #13 by BrewerGuy
If you can’t sort this out, it might be time to reach out to Support, support@singularsound.com to see if they’re aware of anything that could be causing this.
