Terrible things happened to my firefox and thunderbird-gtk2 builds when I used what turned out to be a testing-enabled build chroot to build them.
The builds succeeded but the UI elements blinked in and out constantly and it was uncooperative switching tabs... basically everything fritzed. No idea why... but disabling testing and `pacman -Syuu` allowed the rebuilds to work as expected.
Quickly googling gets me this, which looks like the same issue: https://bugzilla.redhat.com/show_bug.cgi?id=1422532
Hopefully this will get resolved. I filed a bug with mozilla against the failure to respect GTK+2 themes in the 45.8esr to 52 move. (they won't fix). I'll stick with 45.8esr until this is worked out, 52 and GTK+3 on my laptop simply looks horrible (despite trying every dark GTK+3 theme I could find). -- David C. Rankin, J.D.,P.E.
