Hi, if I define the Material.background: "#FAFAFA" with this color, the background is black. Other colors, like this slightly different #FAFAFB, work!

Maybe it correlates with using the Material.theme: Material.Dark

I have attached a demo project. On start the background color is defined with #FAFAFA, but shows black. The switch changes the color to a working color. Putting the switch off restores the problematic color, but works then.

This problem is since Qt 6.9.2.

Best regards, Philipp
