Bug report #15802

QGIS slower and slower after editing

Added by Oskar Karlin over 7 years ago. Updated over 6 years ago.

Affected QGIS version:2.16.3 Regression?:No
Operating System:Mac OS Easy fix?:No
Pull Request or Patch supplied:No Resolution:not reproducable
Crashes QGIS or corrupts data:No Copied to github as #:23722


I am editing a vector layer (SHP) in QGIS. I save edits a lot because of fear of losing changes because the application might crash. What I've noticed is that after a few times of saving it takes longer and longer times to save. The application almost freezes after a while. Same thing happens if I toggle editing on and off. Slower and slower until I can't stand waiting 20 seconds to save the changing of ten vector points. So I have to close QGIS and restart it and then all is fine again. For a while.

This problem has been around for a while (many versions)

Problem may caused through installed cad plugins
See #13869

"rectangles, ovals,..." Is another plugin which causes this behaviour

Yep, several plugins reregister on events/signals on edit saves. OR other logic doing weird things with data...

So please: check if you can do the edits without any plugins.

Either rename you .qgis2 folder temporarily (so QGIS creates a new one) and do you edits.

IF that works, try to add your plugins one by one to find out what is the bad guy, and contact the dev of that plugin.

Please let us know if it solves your problem

The plugin "Numerical Digitize" also caused this affect in my case. It also has the problem that it reregisteres the editingStarted() signal everytime you save the layer.
