--- Comment #1 from Fujii Hironori <Hironori.Fujii at sony.com> ---
ANGLE D3D renderer isn't thread-safe.
PlatformDisplay was destructed in IPC thread.
This is not expected for WinCairo.

WinCairo shouldn't destruct PlatformDisplay because it can cause crash (Bug 170331).

PlatformDisplay::sharedDisplay has 
static variable of std::unique_ptr<PlatformDisplay>.
This triggers PlatformDisplay dtor.
This is not expected for WinCairo.
