Linux does work differently than Mac or Windows but the X coordinate returned by View can still be negative if the window is partially off the left edge of the leftmost screen. But in that case the Window's X coordinate will also be negative so subtracting it out will generate the correct widget-relative location. So I suggest removing the conditional checks here.

Removed (the negative checks)
