Description

There is an issue with large complex vectors and the Select by Location tool.

I have a polygon which has 350,000 nodes and 1200 multiparts. It is the way flood data in Scotland is provided by the environment agency. Performing a select by location causes the system to slow and eventually crash. There is no error message.
