Activating [x] show error when analysis a layer via topology checker draws a big opaque rectangle covering the whole extend of the analyzed layer. That's an important user experience regression as the default behavior is to show errors.

I couldn't find a place to file an issue for the topology checker (no information given on the plugin), and since it's referred to in the QGIS documentation, I'm using the QGIS issue reporter. Correct me if I'm wrong :)

I cannot replicate.

What rule/s dod you used? can you attach sample data? thanks!

Steps to reproduce:

1. Create a new project
2. Open the attached provinces.shp dataset
3. Open the topology checker panel, and configure it with the following rule:
   ** provinces -> must have no gaps
4. When the rule is added, proceed with validation by clicking on the 'Validate All' button
5. When the validation is done, 160-something errors are detected, and an opaque red rectangle is drawn covering the full extend of the layer (whereas the errors are not)

Let me know if that's not sufficient.

yes I can replicate the "red rectangle" with your data, but not with other data also with a lot of errors (gaps and others). Seems this behaviour is triggered by something specific in your dataset, but I don't have much time to investigate right now.
