Comment 194 for bug 1098334

I've not yet tested patch from comment 165 - but with regards to Firefox and Cairo - I'm also seeing errors in i.e. pidgin - where status icons looks occasionally damaged.

And my rawhide has these related packages:

So while the Firefox is the easiest one to see those errors (it's always enough to play for a while with some input box), it's probably not tied with its built-in version of Cairo library.
