Thanks for the info, I didn't know of XUL technical details. Still, if the issue is local to Thunderbird, it's still very likely a bug in whatever XUL uses to render via GTK. For example, LibreOffice tries to use GTK rendering too (GTK3 as of late) and it's not 100% compatible either. I'd try to bug Ubuntu Mozilla Team or maybe upstream developers directly. Just FYI, Murrine developer is https://launchpad.net/~cimi
