Wrong display of objects on viewport and detail views

I have a pack of problems:

  • Jaggy surface displayed on Technical display mode.
  • The jaggy edges keep showing on other detail views despite I have hidden them in that detail and I am unable to be selected.
  • Other objects that have not the first problem have the second one when I hide them on the details (keep appearing on other detail views and are unable to select).

There are no bad objects (I used Analyze>Diagnostics>Select bad objects).

Any guess what may be happening?
