On starting the boinc manager, the window seems to have a screen draw error. There is a small black box with a single blue pixel overlying the top left corner of the window, partially obscuring the Notices tab. The box will disappear if the window is maximized and if returned to a window. It will reappear after closing the boinc manager and relaunching most times.

This bug is triggered by appmenu-gtk: removing this package (and rebooting) will fix this graphical glitch.
Resizing the window in general will fix it (no need to maximize and restore it explicitly).
