Widget parameters appear jumbled in the Details Panel

My widgets like to do this in 4.24 and 4.25:

In the above (button) example:

  • certain fields appear more than once and are non-functional
  • it happens to some widgets, not to others
  • creating a new widget and adding a button results in the exact same behaviour
  • resetting layout does not help
  • it does not affect newly created projects

No clue how to provide repro steps. Hoping someone else experienced it and knows how to make it OK again without reinstalling the engine; and / or knows the way how to reproduce it so it can be reported properly.


To clarify. On the left: a button working correctly; on the right: the weirdness I’m dealing with:

It seems that what should be a part of the button style now also appears outside of its intended category, as a separate entity…

And here’s the culprit.

Do not enable this feature in 4.25, it’s truly experimental…
