Thank you really much for this feedback, we didn't see this bug before!
Can you please confirm me your OS / Browser version?
Thank you for your help!
i have the same thing. i am using Chrome
Chrome on Windows 8 here myself, same issue.
It's the "Proxima Nova" font, it doesn't render in Chrome (it doesn't exist in Windows by default AFAICS) and it doesn't fall back to Helvetica as intended.
I can also find no way to see completed tasks, making this 100% useless. When can we expect this fixed?
