Timestamps overlap sometimes

[MaxGabriel]

I'm not sure what causes this or how to reproduce, but occasionally I look at an EKG graph and all the timestamps are overlapping. There appear to be various degrees of overlap: sometimes it looks like just two numbers overlapping (can still make out the numbers), and sometimes it look like a dozen timestamps are overlapping (can't read it at all).

• I'm using LTS Haskell 5.10 (ekg-0.4.0.9)
• On a 15" retina macbook pro running OS X El Capitan
• Using Google Chrome 49.0.2623.87 (64-bit)

Edit: I mostly notice this when leaving the browser and coming back later. The issue eventually self-corrects itself, too.
