AttachedCardShadow causes WinUI3 App to crash (HP RP7)

[DominicMaas]

Describe the bug

I think this very much depends on the machine, but I was having issues with AttachedCardShadow on a kiosk (never encountered this before).

Faulting module name: KERNELBASE.dll, version: 10.0.19041.1706, time stamp: 0x458acb5b
Exception code: 0xc000027b

When I run the application via VS Remote Debugging, the app simply throws an unhandled exception:
Exception Message: ".ctor"
Message: "Exception has been thrown by the target of an invocation."

Maybe has something to do with Win2D? (This is what I see before the crash).

Using AttachedDropShadow or no shadow causes the application to run correctly.

I wonder if it's a GPU issue?

Regression

Additional context

This issue is a bit of a stub at the moment (due to the nature of the crash), but I'm hoping this may help people in the future trying to debug this native crash (via keywords and google search).

I've managed to work around the issue for this application (only runs on a small set of devices) by using the other type of shadow, only concern would be if this issue is more widespread amongst consumer machines, or if it's only these older POS Retail machines that have the issue.

Hello DominicMaas, thank you for opening an issue with us!

I have automatically added a "needs triage" label to help get things started. Our team will analyze and investigate the issue, and escalate it to the relevant team if possible. Other community members may also look into the issue and provide feedback 🙌

[michael-hawker]

@DominicMaas according to the output it looks like you have 'Just My Code' enabled? Can you try disabling that and changing the debug mode in the properties to be Mixed (Native and Managed):

That should hopefully let you load more symbols for Win2D and WinUI in the stack traces to help us see more of what might be going on?

FYI @Ryken100 if you have any other thoughts on getting more info or what might be going on here?

[DominicMaas]

When I have the chance, I'll try that. (Don't have access to the machine anymore though). I did notice that this appeared in AppCenter (I think related??)

Thanks @DominicMaas if that's the same issue, that stack is more useful.

That'd be this bit of code here:

WindowsCommunityToolkit/CommunityToolkit.WinUI.UI.Media/Shadows/AttachedCardShadow.cs

Lines 107 to 123 in a10204e

	protected override CompositionClip GetShadowClip(AttachedShadowElementContext context)
	{
	// The way this shadow works without the need to project on another element is because
	// we're clipping the inner part of the shadow which would be cast on the element
	// itself away. This method is creating an outline so that we are only showing the
	// parts of the shadow that are outside the element's context.
	// Note: This does cause an issue if the element does clip itself to its bounds, as then
	// the shadowed area is clipped as well.
	var pathGeom = context.GetResource(PathGeometryResourceKey) ??
	context.AddResource(PathGeometryResourceKey, context.Compositor.CreatePathGeometry());
	var clip = context.GetResource(ClipResourceKey) ?? context.AddResource(ClipResourceKey, context.Compositor.CreateGeometricClip(pathGeom));
	// Create rounded rectangle geometry at a larger size that compensates for the size of the stroke,
	// as we want the inside edge of the stroke to match the edges of the element.
	// Additionally, the inside edge of the stroke will have a smaller radius than the radius we specified.
	// Using "(StrokeThickness / 2) + Radius" as our rectangle's radius will give us an inside stroke radius that matches the radius we want.
	var canvasRectangle = CanvasGeometry.CreateRoundedRectangle(

@Ryken100 there shouldn't be any special case here, eh? @azchohfi thoughts on how this could fail on a particular device with Win2D and WinUI 3?

[azchohfi]

Yeah, we had that issue before.
CommunityToolkit/Windows#207
and
microsoft/Win2D#831

I'll ask the Win2D team if this is planned to be fixed anytime soon.

[michael-hawker]

@DominicMaas is this taking down your app? Can you see if the appxmanifest suggestion from the Win2D thread here resolves your issue?
