Windowscommunitytoolkit: Infinite Canvas crashing on Win10 1903 (18898.1000)

[RobbyRobbyRobby]

I'm submitting a...

I have found that the Infinite Canvas control crashes on new insider builds of Windows 10.

It crashes my apps, but is also visible in the Toolkit sample available from the store.

I have a stack dump from AppCenter of my app to help below.

This has worked up until now.

Current behavior

Open a page with the infinite canvas, ink away on it and eventually (not normally very long) it will stop responding and then crash the app entirely.

App center reports it as:
surfacebaserender_surfacedefaultrender_ onstrokemodified()
heap_corruption_clrsetup_mscorlibmismatch C0000374: heap_corruption_clrsetup_mscorlibmismatch

Expected behavior

As above, but without the crashing :-)

Minimal reproduction of the problem with instructions

The Toolkit sample exhibits this behaviour.
Otherwise you can just put the canvas on a page and run it.

Environment

Nuget Package(s):
I have tried this with the same result in the current version 5.1.1, 5.1.0, 5.0.0 all with the same result.

Other apps using Ink are not crashing (OneNote for example) and other apps using this control which didn't crash before are now crashing.

Windows 10 Build Number:

• Current Windows Insider Fast (18898)

App min and target version:

Fall Creators Update (16299) and later

Device form factor:

• Desktop

Visual Studio

• 2019

Thanks @RobbyRobbyRobby have you filed a Feedback Hub item as well? I'm wondering what's changed in the OS that has maybe caused an issue. Does the regular Ink Canvas give you any trouble?

@IbraheemOsama any insights?

[Kyaa-dost]

This is still occurring as within a couple of mins of drawing the sample app easily crashes.

@deanchalk any insight on this? 🤔

I'm afraid that's a mystery to me. The Issue I looked at previously mentioned heap corruption - which I couldn't reproduce, but I did find (and code a workaround) for another issue that made the infinite canvas crash. I was not on any insider preview. Unfortunately, I can't put myself on the insider fast ring as it makes my laptop unusable (I've recently had to rebuild it to get off the insider program). If you want me to take another look I can try, but I couldn't reproduce the issue last time

No-Repro in v6.0.
It seems probable that Dean's theory is correct and this has been resolved with a previous PR.

I spent quite a bit of time (as well as @Kyaa-dost ) scribbling in the canvas without a crash.

I will close this for now. Please reopen if there is a regression. Thank you!
