Rathole

I spent most of the day tracking down and isolating a bug where tooltips shifted by 1 pixel.

Experience it for yourself in this gif. In some cases, it can be more severe, but mostly it was just annoying.

Even after spending the day, I didn't find a solid solution. But at least I was able to isolate the problem and report it at the source. If I'm lucky, some benevolent soul on the AngularUI team will fix the bug and I'll be rewarded for my diligence, but it's also just as likely it'll slip through the cracks and I'll have to come up with a workaround. Or try to solve it well and submit a pull request, but I really don't like the sound of that. I've got enough problems on my own.

At least it was only one day. I've spent more time on smaller problems. I find it hard to know where to draw the line with troubleshooting. Sometimes I take it too far, but that moment when the clouds part and you finally understand the problem, it's so good.
