I'm using QGIS 1.8 on Ubuntu 12.04. If I add a polygon layer in SHP format and WGS84 projection and start to zoom in, from a scale of 1:200.000 aprox. polygons on the edges are not drawn anymore and if I zoom in closer than none of the polygons are drawn. The same SHP converted to UTM ED50 zone 30 renders without any problems. The same layer in WGS84 with QGIS 1.8 on Windows 7 renders without any problems. Is there any known bug regarding this issue?

Can you share the data? There is no known issue about this particular case, and i use regularly wgs84 data on linux without problems. So I guess it may be related to a particular dataset. – Giovanni Manghi Aug 16 '12 at 12:22
I can give you the SHP of the provinces of Spain in WGS84. How can I pass you a zip file? – michielz Aug 16 '12 at 12:52
dropbox? ubuntuone? if is not too big you can send me to giovanni dot manghi @ faunalia dot pt – Giovanni Manghi Aug 16 '12 at 15:44
I have pasted a zip in dropbox -> You can download it and take a look. I think the problem is related to my Ubuntu machine and other layers in WGS have the same problem on that machine. I did not notice this earlier. Since first installing QGIS I have added an installation of PostGIS on the same machine. Could it be that this instalation has caused problems? For example to the GDAL or projection definitions? – michielz Aug 17 '12 at 7:59
Just tested your data on Ubuntu 12.04 64bit and I have no problem whatsoever. What is the project CRS that you are using? Is a projected CRS and do you have on the fly reprojection enabled? – Giovanni Manghi Aug 17 '12 at 8:59
