@deg @timok PLUS ANYONE USING re-frame-10x https://github.com/Day8/re-frame-10x/blob/master/README.md#the-expansion-triangles-in-the-data-browsers-dont-work-any-more-but-they-used-to

Thanks @mikethompson I definitely had that issue. Will verify and confirm that fix when I can.

I wrote about the performance problems yesterday. I have found the cause in the one of my interface element. It is a long list of elements that mount in DOM within slide-menu (It slide from a left side). I read this https://github.com/Day8/re-frame/blob/master/docs/Solve-the-CPU-hog-problem.md And did the list rendering after the slide menu slide from a left side of a page

And it improved performance

Thanks @mikethompson I suffered from it too

I hope this will help

Probably for better performance it will helpful to use: https://github.com/bvaughn/react-virtualized I hope It has a good compatibility with reagent

looks like I’m hitting https://github.com/Day8/re-frame-debux/issues/22 in my app. Does anybody know a workaround? Should I convert my code to not use cond->?
