when i use a panel height >= 26, then the menu button in the panel has some kind of border on the inside that cuts the top and the bottom of the icon. tasklist buttons aren't however, so it must work without those borders. please remove them.
I can confirm this bug. My personal (ugly) workaround is to set an (empty) label to be displayed besides the icon. If the label is missing the icon is cut off at the borders.
I can confirm this bug as well, however, the workaround doesn't solve it. The workaround solves the cut-off at the left and right sides of the icon, but not at the top or bottom. Launchers doesn't have this problem, it's only with menus plugins.
