Steps to reproduce the problem:
I have switched my password store from "gnome" to "basic". This solves the issue that I have to wait ~30 seconds for a passwort to appear on a website.

But now the "Stored passwords" dialog in settings is incredible slow. It opens, then blocks for ~30 seconds and then behaves extremely slow. Even the mouseover effect has a delay of ~5-10 seconds.

On startup I get this error, no idea if it's related or not:

[30633:30669:1028/140735:ERROR:generic_change_processor.cc(401)] Autofill datatype error was encountered: Failed to delete Autofill node. Local data. ActOnChanges@../../components/autofill/core/browser/webdata/autocomplete_syncable_service.cc:393could not find entry matching the lookup criteria.
[30633:30669:1028/140735:ERROR:generic_change_processor.cc(340)] Delete: Bad entry.
[30633:30669:1028/140735:ERROR:shared_change_processor.cc(112)] Change processor disconnected.

I have ~1000 passwords in my password store (the file is ~350kb in size). If I filter, the dialog behaves much better.

What is the expected behavior?
Dialog should be fast

What went wrong?
Dialog should is terrible slow

Did this work before? N/A
