MiniProfiler HTML widget very slow in Chrome on Retina Macbook (includes workaround!)

[mipearson]

Writing this up as this was a biig problem for me when using MiniProfiler.

MiniProfiler's use of a position: fixed widget causes extreme slowdown when trying to scroll certain pages on Chrome on a Retina display Macbook.

The workaround is as follows:

1. Enter about:flags in your chrome browser bar
2. Set "Fixed position elements create stacking contexts. " to "Enabled"
3. Set "Compositing for fixed position elements." to "Enabled"

Once again enjoy smooth(-ish) scrolling!

getting away from position fixed is not really an option without a massive redesign

I think I would like to close this issue, not much we can do.

I agree that there isn't really a fix: I recommend adding this to the documentation somewhere. I raised it as an issue rather than a PR as I'm not sure where you should add it.
