WinAppSDK 1.1.4 application rendering blank for subset of users

[crutkas]

Describe the bug

microsoft/PowerToys#20502

We have a set of users that have WinAppSDK apps render blank. We are on 1.1.4. Users have confirmed the exact break was when we did shift from a XAML Island to a WinAppSDK.

Our applications are unpackaged.

Steps to reproduce the bug

Small subset of users are reporting the issue. We are uncertain what is actually causing it. The body renders and at times, one icon.

Expected behavior

application renders correctly

It's a kind of broad bug, as I saw this bug in late 2010-s in any UWP apps

A fix for the core issue is included in the 1.3 release.
