-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
I ran into similar issues with very large polygons. It was a clipping problem. I believe it was fixed with a patched qt version in the windows version, but if you use the original qt packages from ubuntu, the fix wouldn't be present. Are you using old or new symbology? I believe the issue is not present any more in the new symbology. If it still is - would you be willing to share the dataset with the geometry that causes the problem? Marco perhaps could have a look at it. btw: your machine seems very powerful to me. It really shouldn't be a hardware issue.
