CodeMirror2 is slow in webkit

[chiel]

Hi Marijn,

When using CodeMirror2 in Chrome/Safari, it responds very, very slowly to text input, and the cursor remains at the left of the textarea at all times, even after the text appears. Couldn't find an issue about this specifically.

Best,
Chiel

I develop on Chrome, and for me it's faster than any other browser. Please give an exact version and platform, and describe what you are doing.

Hmm... must be something on my end then, I'll try figure this one out. Consider this report faulty, for now. Sorry. :)

Trying to find the bug, but I must admit it is hard. Your demos work just fine in my chrome, so it MUST be something on my end.... now to find out what exactly.

Is there anything CodeMirror is especially prone to, or so, that can get me started on figuring this one out?

Thanks in advance.

Nothing comes to mind. It could be something really stupid—this codebase is very new. So yeah, just reduce the complexity of your test one step at a time until you find the relevant difference. (You don't want to know how often I've had to do this for CodeMirror 1.)

Yeah, it's tied in to some mootools stuff I'm doing, so I'll just have to change some stuff around to make a suitable test. Thanks for the great library, though! :)

I reopened this as issue #48, with the cause highlighted.
