I discovered a somewhat unimportant bug related to the taskbar being set to auto-hide. It breaks the OSDs (on screen displays). When the volume or screen brightness button is pressed, the OSD does not display. This is what I've discovered about it so far: if (taskbar = showing) OSDs work. if (taskbar != showing) OSDs are broken. if (any notification = showing) OSDs work. It does not matter if the taskbar is set to auto-hide or show always. As long as it is currently showing on the screen, the OSDs will display as they're supposed to. Notifications seem to affect the OSDs in the same way.
this has been recently fixed in master
