Creating spatial index on Shapefile with invalid geometries will make the layer disappear in map canvas when zooming and panning

Original Redmine Issue: 13419
Affected QGIS version: master
Redmine category:map_canvas

---

I've got one file which behaves strangely when associated with a spatial index. When I zoom in, the layer disappears from the project and from any opened composers. If I remove the .qix file, the display is ok. If I re-create in qGIS the index (layer properties/Create spatial index) the layer goes back to its random behaviour.

Thanks for the sample data.

I can confirm the issue although the attached testcase seems to have invalid geometries.

I can confirm that it doesn't happen with shapefile with correct geometries.
