Bug report #9010

Updated by Giovanni Manghi almost 3 years ago

1) Start QGIS - Add a layer in EPSG:27700 (British National Grid). 27700 is my qgis default projection.

2) Ensure "enable OTF CRS transformatioN" is checked.

3) Add this layer - http://geocommons.com/overlays/5603

4) Zoom out.

At a certain point, you end up with something like the attached. Worse, QGIS takes about 5-10 seconds to calculate this - using an entire core of my CPU to do so.

ArcGIS output for the same is also attached.
