Is this only on the sidebar and details layout?

Is this only on the sidebar and details layout?

This is what UIElement.HighContrastAdjustment will handle

So all controls using UIElement have this issue.

@0x5bfa

@yaira2 By default they want to prioritise the readability of text. But because it is not visually appealing, they allow you to set the High Contrast Adjustment - to remove this behaviour | as long as the app developer has ensured the text contrast is readable.

If you want to remove the backplate, check every element to ensure text is always readable

This is the Tab control as an example, from when they fixed the issue in the controls

[yaira2]

So is the expected design to have black text without a backplate?

Anything highlighted, needs the correct text colour.

There appears to be an issue where setting the property in app.xaml doesn't work. We can work around by setting it on the individual page, but we'd prefer to avoid doing this.

I should work though, when I tried last time I worked well. But Dialog class and MenuFlyout class doesn't respect this setting in App.xaml so need to set indivisually or we can find another way if any.

@0x5bfa it's not too bad if it's just dialogs and menu flyouts. Let's do this 👍

Alright!

[yaira2]

This should be resolved in main.
