After settings_ui() was recently changed, it seems that visuals_mut() cannot be set.

I haven't looked into it in detail yet.

    ui.visuals_mut().widgets.hovered.fg_stroke.color = hovered_color;
    ui.visuals_mut().widgets.active.fg_stroke.color = active_color;
    ui.visuals_mut().text_cursor.on_duration = 1.0;
    ui.visuals_mut().text_cursor.off_duration = 0.3;

What is certain is that until a few days ago, when I applied the following to change the scrollbar color of ScrollArea, it worked fine, but now it does not work.

Changing the value only once will reset it.
If you always change a value within the UI, the changed value will be retained.

    let hovered_color = egui::Color32::LIGHT_RED;
    let active_color = egui::Color32::LIGHT_BLUE;

    ui.visuals_mut().widgets.hovered.fg_stroke.color = hovered_color;
    ui.visuals_mut().widgets.active.fg_stroke.color = active_color;

This is expected to be a symptom caused by converting dark() and lignt() of egui/src/style.rs to default values.

It seems that items unrelated to dark() and light() should be separated and maintain their values.

Could it be because of this?

Or maybe it's for some other reason?

I haven't verified that #4744 solves the issue, but it seems likely.
