Description
Reproduce:
0. Build the (very simple) desktop application from the sources attached: CrashOnResize_sources.7z
1. Ensure there is an Internet connection. Run the application.
2. Reduce the window width several times (2—5), preferably once the web view fully accommodated for the previous one.
Expected: no crashes.
Actual: eventually, a crash happens:
