I am able to reproduce this problem every time by killing notification- daemon and running a test program that opens a notification near the bottom of the screen.
I.e. the very first notification opened by an instance of notification- daemon suffers from this problem. I'll try to find the offending code later, if i'm feeling well enough. -- Panel notification appears too low, distorts bubble https://launchpad.net/bugs/46642 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
