Sandcastle lagging and figures not lined up #42602

Open ghost opened 11 years ago

ghost commented 11 years ago

On the sandcastle, when I open an exercise, the numbers will slowly appear one by one. Also, the diagrams will not match up with the numbers; the numbers will be in the wrong place. This is only an issue with the sandcastle, though; the live site is fine.

No need to say realbug when the issue is opened directly on GitHub. :)

Does this happen consistently for every exercise or only for some?

It has happened on at least 2: One was a multiplication/division/addition/subtraction (I'm not sure which) the numbers were not lined up with the line, and each number slowly appeared 1 by 1 The other was something like area of quadrilaterals, and the angles and side lengths were way off of the figure. These numbers also slowly appeared. I will try some more to see if it happens again.

graphing parabolas 0.5 The numbers on the axes are all shifted down and to the right. Number are again appearing one at a time, very slowly.

I noticed this too the other day: http://www.youtube.com/watch?v=Y0mVhPAuYlY

Doesn't happen in my local environment either. Only on sandcastle. Not sure what's going on. Mathjax.Hub.queue.queue.length confirms there's a bunch of stuff in the queue and you can watch it slowly count down, but no idea why it's taking so long:
