I had a similar problem recently with some downloaded boundary data
shapefiles which wouldn't display properly in QGIS 2.2 or 2.4 on Windows 7
Professional 64x - some layers didn't display at all, others had missing
polygons.  The data provider suggested I create a spatial index (under layer
properties - general) and it solved the issue.
