Select Points Through slowed down by Find Data
Steps to reproduce:
- Create Sphere source
- Set Phi resolution to 800
- Use Select Points Through and select bottom half of sphere
- Open Find Data dialog
- Close Find Data dialog (no need to do anything beyond this)
- Use Select Points Through to roughly select the same points again
The first Select Points Through is significantly faster than the second one. Note that this difference may not be that noticeable if the Select Points Through is very fast. This has been noticed on both Linux and Windows with PV 5.2.
