layers not rendered (or partially rendered) in qgis master

Original Redmine Issue: 9426
Affected QGIS version: master
Redmine category:vectors
Assignee: Alvaro Huarte

I just compiled from source the latest code and have issues with the attached vectors (try zoom in).

This does not seems the same issue filed (and closed) a few days ago that had a similar description but happened when activating simplification, because in this case it happen also with simplification off. It seems anyway that it may be simplification related.

after making a whatever editing operation the vectors do render correctly, so maybe after all is a data issue(?). Not sure about that, they un-edited data shows fine in qgis 2.0.1

Hi, I have tested the data and ArcView 3.1 crash! I edited the code for QGIS does not use the current map extent to filter the data and then the layers are showed.

I think that there is a problem when the current map extent is converted to layer coordinates in....

I study the code

Hi Giovanni, if I create the spatial index and update the extent from layer properties panel, it works fine!

ok, maybe is a corrupted index. closing as invalid

But, If spatial index does not exit it works bad, may spatial index lib throws these issue ?
I am going study it
