[Qgis-user] Display problem

[Błażej Zamojski]

Hi
I have a problem with vector data display in QGIS (from shapefile on 1.7.3
standalone, WinXP). When I'm zooming into some areas on the map I get a
result like in attachments. This problem is seen with polygons that cover
big area (i.e. 1st one is covering more than 3600 km2). For the first
attachment problem starts at 1:8500, but at second at 1:4300. Is it a known
bug, something new or there are some errors with data I am using?
