[Gnome 3.26] remove black dot under app-menu-icon

[benjamindaines]

Under gnome 3.26 when hiding the app-menu-icon by setting height, width, margin-left, margin-right a false shadow is created where the icon should be. This can be fixed by adding color: transparent;

#panel .panel-button .app-menu-icon {
      width: 0;
      height: 0;
      margin-left: 0px;
      margin-right: 0px;
      color: transparent; }

This is caused by icon-shadow being applied to panel button icons on :hover with 3.26 shell theme. It also effects system status area icons, that have shadow on :hover.

Here's a proper fix for both issues: (removed)

The fix in my previous post was incomplete, as there were still shadows in panel icons and text when there's no maximized windows, i.e. when panel is transparent with the default shell theme.

Here's a new patch that should fix all icon/text shadow's in panel: gnome-shell-3.26-panel-button-fix.txt
