Description

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.

#1 Updated by Giovanni Manghi almost 6 years ago

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

#2 Updated by Alvaro Huarte almost 6 years ago

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!

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

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