I had some success with setting the environment variable QT_GRAPHICSSYSTEM to some value (e.g. 1).
The problem seems to be triggered by the line QApplication::setGraphicsSystem("raster") in unity2dapplication.cpp:144 (http://bazaar.launchpad.net/~unity-2d- team/unity-2d/trunk/view/head:/libunity-2d- private/src/unity2dapplication.cpp#L144). There is a long comment above this statement which explains why this method is used but maybe a unity- developer with more insight could look into this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/979756 Title: Top bar w/ radiance theme shows ugly colored fringe (unity2D and, to a lesser extent, unity3D) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity-2d/+bug/979756/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
