Can't adjust Backface Colour on surfaces

[Bako_Nagy_LTD]

Hi,
Using Rhino WIP 9.0.25259.12305, 2025-09-16, I cannot change the Backface Colour for surfaces. Steps: select a surface → try to change Backface Colour → no effect.

OS: Windows 11, 64-bit
Thanks!

Thank you for your feedback. It appears this is a bug with the color backface options in the current Display Panel. For now, you need to enter the display mode to set it, as demo below.
