Version: 2.7
Recently, one of my juniors faced this issue. Whenever she was adding a polygon feature layer, it was displayed as a blob. I was baffled.
I made the filling hollow and turned the outline width really down to 0.7 Pt. The error remained. When I did not use any color for the boundary but for the filling, the polygon was correctly displayed. I wanted to reproject but I did not as it was all good with the filled shape.
I checked the shapefile with ArcMap and G-Earth (+ QGIS). The layer was properly shown. Is it a bug with 2.7?
Solution?
