I have an old project that is painful to edit with topological editing activated. I put a couple of the layers into a new project and topological editing is very quick. Specifically, in the old project, moving a single node on a polygon with the vertex tool that does not require any additional vertices to be moved takes about 2 minutes to complete but is nearly instantaneous in the new project.
As a test I deleted all but two layers from the old project and it's still unacceptably slow. So I'm pretty sure I have something amiss in my old project. An obvious solution would be to build a new project but I'm kind of lazy and it would be nice to know what I'm doing wrong. I've looked at all of my snap settings and I believe they are the same between the fast and slow project. I'm running QGIS 3.30 and the layers are in a PostGIS db. Thanks for reading.
