I can confirm that this is a duplicate of https://bugzilla.mozilla.org/show_bug.cgi?id=1136417 . Compiling x11-libs/cairo without "xlib-xcb" in USE is a valid workaround. Thanks, _AxS_, for helping on this! :)
Leaving open since it's a random issue which may depend on lots of random factors. However, xlib-xcb on cairo has its own bug 441878 tracking issues with and without that flag.
I have this bug on firefox-43, not sure how to fix, very annoying
I have read about this bug elsewhere and I remember it being related to some color transition effects (degradè/crossfading) used on the about:newtab page, and not present on about:blank.
If you feel I have closed your bug and it is still a current issue, please reopen and update it completely. We will not work bugs that have no ebuild in tree any longer or can not be reproduced with a current system. Thank You for your support and understanding The Mozilla Team
