Description
I have a form with 9 relation reference widgets.
With current master, these widgets randomly show either the internal numeric code (within parenthesis) or the human-readable text that is meant to display. Sometimes the text, sometimes the numerical code. Randomly, even when used on the same feature.
In screenshot 1, the widgets labeled "Gewässerkategorie" and "Rechtszustand (Wasserbauverordnung)" show the internal code.
In screenshot 2 (same feature, two seconds later), the widgets labeled "Art Gewässerabschnitt", "Gewässerkategorie", "Verlauf (offen|unterirdisch)" and "Rechtszustand" show the internal code.
In a third or fourth try even other widgets randomly show either text or internal code.

I should add that in the attribute table I can always see the human-readable represent value as expected.

New finding:
On another machine, where the PostgreSQL database is on the same machine like QGIS as a client, the widgets always display fine. In my initial setup the PostgreSQL DB is in the same LAN, but on a different machine.
So I wonder if the issue has something to do with the speed of the database connection?
The slower the DB-connection the less likely the values in the relation reference widgets display fine?
Would that explain things?

For some additional information, here are the exact build numbers I tested:
edcaf05bcb (on Windows - issue is reproducible) and ee59abf030 (on Linux, with DB on same machine, issue not reproducible)

The issue doesn't appear anymore. Perhaps it was a side effect of something else.
Closing it now.
