I have a div with overflow on it to allow the calendar to scroll. But in FF 17, it seems to have a rendering problem that appears if you scroll up. The top of the page simply repeats inside (image attached). He corrects himself in a few seconds.
Several boards on the Internet have suggested including this in approximately: config (gfx.direct2d.force-enabled layers.acceleration.force support webgl.force-enabled), which fixes the problem, but is not really a viable option for clients using web Appendix.
This question here iframe will not scroll in Firefox 17 , it seems that there are problems with not scrolling at all, so close, but not quite.

Does anyone else come across this or have an idea on how to fix it?
