Which dialog is the screen shot of ? The "Do you want to save" dialog is definitely rock solid for me with no corruption.

I don't remember what dialog it was. however, the issue can be reproduced simply by displaying license information (help->license information).
This one is from oowriter (te same issue in oocalc).

sometimes only part of the dialog displays with corrupted fonts. The following happens every time I try to copy-paste text(with newlines and tabs/spaces) into oocalc.

gtk3 backend is unaffected, only the gtk2 one. Double checking with old versions of libreoffice 4.0.0 those are also affected if run on fedora 23, so seems that whatever the problem is is, its not a regression on our side. Either it was "always wrong, but worked", or some other component has broken. My money is on some XRendr problem.
we're drawing the text with cairo, interestingly if I add an additional debugging draw + clear of a pixel via cairo_fill to that xlib surface before drawing the text, then it renders perfectly fine.
I'll try and extract a standalone demo unless the rings a bell with anyone.
can't seem to create a standalone example. I can tell that if I build cairo with --enable-xlib-xrender=no then it also works fine, so the problem is in that direction
I'll just bodge this to work for now. Still unsure what the core reason actually is.
