Undoing a change to a selected resizable UI element while ShowDevelopmentGui is off will throw errors

Bug Reports Studio Bugs

For simplicity, I’ll refer to this button image as the “Secondary Visibility Toggle”.

Bug:
Undoing a change to a selected resizable UI element while ShowDevelopmentGui is off will error. It happens 100% of the time.

Steps to reproduce:

  • Select a UI element that can be resized.
  • Change one if its properties.
  • Toggle ShowDevelopmentGui off using the Secondary Visibility Toggle (while keeping the UI element selected).
  • Undo the change. (CTRL+Z)
  • Observe output for error messages.
