I tested the pubished Ubuntu Wily binary packages Friday night, same results in gtk3.17: a nasty black border around all of GNOME's CSD applications and no shadows in application popup windows. Shadows and other composited effected seemed fine on server-side decorated windows but not popup windows of any kind, which gtk now sees as csd windows.
At least I was able to force transparency support in my customised MATE build (with 3 lines of added source code per affected window), but GTK 3.17 at least is still not detecting by default that Compiz is a composiitng window manager. It appears that the temporary fix GTK used in 3.16 (no borders but no compositing or shadows) may have been reverted based on those borders, similar to those that appeared with gtk3.15. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1436553 Title: Transparent windows render black with Gtk3.16 and compiz To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1436553/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
