Bug ID: 35701
           Summary: League of Legends: Right click contextual menu on
                    friends list is invisible
           Product: Wine
           Version: 1.7.13
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal

When I open League of Legends, and I open the friends list, you can right click
on a friend to do things such as remove, spectate, message, etc, however in
Wine (as of 1.7.13) this contextual menu is invisible. Items in the menu are
still clickable, if you know where to click them. No crash or anything occurs,
just an invisible menu.

This occurs both with and without compositing enabled, and I've seen it
occurring on both Nvidia proprietary drivers as well as RadeonSI Mesa drivers.

No output is given to the console when I right-click on the friends list.
