Hello, Last few months, I have a problem with big tables on my website. Around the middle of the table, the boxes overlap. If I refresh the page, the boxes are correctly positioned but the background is black (it should be white). I installed the latest version of Firefox (beta) and the problem seemed fixed. But since yesterday (I think), the bug is present again. I know it is not present in everyone, but I do not know why. And with other browsers (I tested IE and Chrome), there is no problem. Thank you, Cordially, WP (Let me just say that I speak French, I'm sorry if there are faults of language.)

I can reproduce with HWA off.

Sounds like a case of bug 671302.

So, the problem is the background image ? The bug will get solved with the new version ? Can I do something ? Thank you, WP

The link you provided is no longer available, can you please provide another one so I can test this on my end? Also, is this still reproducible on your end ? If yes, can you please retest this using latest FF release and latest Nightly build (https://nightly.mozilla.org/) and report back the results ? When doing this, please use a new clean Firefox profile, maybe even safe mode, to eliminate custom settings as a possible cause (https://goo.gl/PNe90E). Thanks.
