Checkbox visualization on UWP

[BurningAXE]

I think I have found two bugs with the visualization of the checkbox on UWP.
Here is the XAML:
<messier16:Checkbox Checked="{Binding Complete}" TickColor="Yellow" CheckboxBackgroundColor="Green" BackgroundColor="Transparent" WidthRequest="30" HeightRequest="30" />
And here is how it looks like:

As you can see the colors are not respected. (They work fine on iOS and Android)
The second problem is that checkboxes that are checked at startup have a checkmark (Subtask 0) but when you toggle one at runtime it just fills with color (Subtask 1). If I toggle Subtask 0 off and on, the checkmark disappears.
Let me know if I'm missing something or if you need further info to debug this!

P.S. Thanks for the nice component :)

Sorry for the late response, I'll start checking it now.

Oh, this sucks. But I think the check colors are somewhat more difficult than I thought. I remember facing this when I developed the control. Basically I think you'll have to customize the theme of your entire application as I can't find a way to set the color of each checkbox individually.

As for the other issue, I'm unable to reproduce it, ¿can you please upload a testable example, if possible a MCVE?

Hey!
About the colors - thanks for the info. I'll keep in mind I need to change the app theme.
About the initial checkmark - I'm attaching a simple project that reproduces the problem. It happens on both mobile and desktop. On desktop the checkmark disappears even by just hovering over it. Let me know if you need further assistance!

Woha, that's a really weird bug. The value of the Checked property persists, it's just the Windows CheckBox the one that has drawing issues.

On desktop if you maximize the window the checkmarks will appear again, it is just weird. Still working on it now I'll try reproduce it on a "native" UWP project.

Aaaaaaand seems like we're not alone: https://stackoverflow.com/questions/41016815/uwp-customrenderer-for-checkbox-pointer-over-checkbox-changes-style

Oh, another Xamarin bug - surprise!
I guess we are left with the wait-and-hope strategy :) In this case this issue is good for closing.

Can you make this work from this fork?

It is taken from that question on stackoverflow.
