Description
There is a new option in layer properties -> digitizing -> Geometry Checks.
When activated and also features count is enabled, it checks geometry for every feature in a layer after every singel vertex edit.
My layer have 20000 features. These checks are very slow.
Shouldn't this feature check geometry validity of a current feature being edited?

I have tested on a 4000 features layers, each with thousands of vertexes and does not seems to be an issue. Can you attach sample data? thanks.

You are right. I found the cause.
When "show feature count" is enabled, layer editing is very slow.
QGIS is recounting features after every vertex edit.

Shouldn't it recount them on saving?
