Sorry for pictures, but this bug appears randomly, I can't provide jsFiddle code, because I don't know how to reproduce it.
Here is part of my site that looks good in major browsers:
Usually it looks good in Chrome, but sometimes I am getting this layout:
This bug appears on all site pages, not just this sample page.
When I try to open development tools and change some layout, bug is eventually dissapear on entire site and I can't reproduce it until make few browser reloads.
I also know that it is old Chrome bug, it is exists at least one year, so I believe that somebody already know solution how to fix it.
Please help me, any help is appreciated.
P.S. I have "clean" browser, without extensions. Other people also see this bug, not only me:).
P.P.S. If somebody want to reproduce this bug - you can follow site (link removed at request) that you see on pictures, but as I told before - it appears sometimes, if it's not appear, close and open browser and try again.
