DrawImage() can not display what I want on game window

Question

I created my project in cpp from scratch, and here is the code I used in main.cpp

#include "Leadwerks.h"
#include "GameControl.h"
using namespace Leadwerks;

int main()
{	
	iVec2 gfxmode = System::GetGraphicsMode(System::CountGraphicsModes() - 1);
	gfxmode.x = Math::Min(700, gfxmode.x);
	gfxmode.y = Math::Round(gfxmode.x * 9 / 16);

	Window* window = Window::Create("CSCDVMP cpp", 600, 600, gfxmode.x, gfxmode.y, Window::Titlebar);
	Context* context = Context::Create(window, 0);
	World* world = World::Create();
	
	Pivot* gameControl = Pivot::Create();
	GameControl* actor = new GameControl(); //this actor has PostRender() which I used to draw image
	gameControl->SetActor(actor);

	while (true)
	{
		if (window->Closed() || window->KeyDown(Key::Escape)) return false;
		Time::Update();
		world->Update();
		world->Render();
		context->Sync();
	}
	return 0;
}

In PostRender() function of my actor

Context::GetCurrent()->DrawImage(
  myimage,
  Window::GetCurrent()->GetWidth() - myimage->GetWidth(),
  0,
  myimage->GetWidth(),
  myimage->GetHeight()
);

as my expectation, myimage will be displayed on the top right corner of screen, but this look like this instead

window size seems to be larger than actual game display. It is ok if I use Window::FullScreen in Window::Create()

Use the context size, not the window size.

I realized that actual window size is smaller than input size in Window::Create(), why ? This does not happen in Lua game
