QGIS has problems with rendering some polygons. To fix some of these drawing issues turning on anti-aliasing seems to deal with the problem. See attached files.

However the map composer does not seem to use anti-aliasing to render the mapcanvas. I suggest that the map composer uses the QGIS application options to determine which method to use during rendering.

I have also uploaded the shape dataset for further testing if required:

Im moving this over to 0.8.2 since we wont have time to address this issue in the 0.8.1 release.


#2 Updated by Maciej Sieczka - almost 16 years ago

  • Resolution set to fixed
  • Status changed from Open to Closed

Same as #83, this bug seem to be gone since 0.10.

Tested under WINE 1.0.0 configured to emulate Win XP, on amd64 Debian testing, with reporter's Shapefile data, using Marco's "QGIS 0.11.0 for Windows pre-release testing installer", and the same machine with native 0.11 GNU/Linux build.

Closing it.
