QGis gets slower while editing

QGis becomes slower after editing a few geometries. When a layer is in edit mode, you start selecting features and deleting them. After a few operations selecting takes several minutes and you need to close the project in order to restart, but again after a few deletions it still hangs.

Tested on win 10 64 bit, osgeo4w install, v. 2.12 (same also in 2.8.3).

plugins CADDigitize and perhaps CadTools seems to produce this behavior.
Time to seve changes or saving the project grows exponential. after five or six changes saved, QGIS is near to freeze (5 Minutes to save edits in a shp-File or spatialite db).
deinstall this plugins helped in my case.
you can also try to start qgis without plugins (insert --noplugins in the qgis.bat file in bin birectory )

Do you have the Advanced digitising enabled?

If so, it is probably related to #21829.

After a few attempts, disabling unnecessary plugins seems to work the problem out. But I'd like to stress the point that working without plugins or with a limited number of them is not a normal user situation

Of course, but it is also not a qgis (core) issue. If you are missing core tools then consider adding them or supporting their development. Cheers!

As Giovanni stated, this is out of our control and not something we can fix. The next steps would be to disable each plugin one-by-one until you can identify the problematic plugin, and then contact the plugin's author and get them to fix the issue.

I'll try without plugins and get back to you!
