This happens because unity (compiz) doesn't advertize to support _GTK_FRAME_HINTS (as we don't), so gtk3 doesn't set up an rgba surface for tooltips and other client-side decorated windows (such as the ones with headerbar, to be fixed differently).
However in unity we do support rgba surfaces, and so to get proper transparent corners we need to force this. ** Branch linked: lp:~3v1n0/gtk/unity-rgba-tooltips -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1508357 Title: Tooltips have a black squares outside of its rounded corners To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/1508357/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
