--- Comment #1 from Fujii Hironori <Hironori.Fujii at sony.com> ---
Thank you very much for the bug reporting.
Can you use Visual Studio debugger?
Can you post a backrace of the crash?

The start page of MiniBrowser is https://webkit.org/ .
This page enables Accelarated Compositing automatically, and uses GPU process.

What will happen in simple pages that don't need Accelarated Compositing?
For example,
> MiniBrowser.exe https://webkit.org/reporting-bugs/

Or, what will happen if you disable GPU process by changing the registry keys.

> reg add HKEY_CURRENT_USER\Software\WebKit /v gpu_process_canvas_rendering /t REG_DWORD /d 0 /f
> reg add HKEY_CURRENT_USER\Software\WebKit /v gpu_process_webgl /t REG_DWORD /d 0 /f

You can restore the original behavior with the following commands:

> reg delete HKEY_CURRENT_USER\Software\WebKit /v gpu_process_canvas_rendering /f
> reg delete HKEY_CURRENT_USER\Software\WebKit /v gpu_process_webgl /f

What about WinCairo WebKit1?

> MiniBrowser.exe --wk1 https://webkit.org/reporting-bugs/
