Screenshot showing Slider with rail/track not painted
On UWP, if the BackgroundColor of a Slider is set (e.g. to Color.White or Color.Yellow), the Slider rail/track is not displayed until the user hovers the mouse pointer over the Slider.
For example, the following code produces the Slider in the attached screenshot. The red arrow points to where the rail/track should be.
Slider slider = new Slider();
slider.BackgroundColor = Color.Yellow;
slider.Maximum = 255;
slider.Minimum = 0;
slider.Value = 0;
I am using XF 126.96.36.199
Checked against the latest 2.3.6 nightly as well where the issue also exists.
This should be fixed on 2.4.1-pre1
