Feature request #15655
Discard from rendering polygon vertices located in the upper left corner

When OTF reprojection is enabled, sometimes coordinates of vertices do not make any sense. Such vertices are then rendered in the upper left corner of map canvas. Although reprojecting world datasets into local coordinate systems makes little sense, such situation hampers creation of overview maps in print composer where in one map canvas is shown particular area but in another - part of the world showing the area of interest.
The most easy solution would be discarding vertices with "impossible" coordinates thus avoiding annoying lines running all over the canvas to the upper left corner (see attachment for an example).
