Here's the relevant bits of code - error handling etc. is omitted for clarity.

 D2D1_BITMAP_PROPERTIES1 bp;
 bp.pixelFormat.format = DXGI_FORMAT_B8G8R8A8_UNORM;
 bp.pixelFormat.alphaMode = D2D1_ALPHA_MODE_IGNORE;
 bp.dpiX = 96.0f;
 bp.dpiY = 96.0f;
 bp.bitmapOptions = D2D1_BITMAP_OPTIONS_TARGET | D2D1_BITMAP_OPTIONS_CANNOT_DRAW;
 bp.colorContext = nullptr;

 ...

 d2dDeviceContext->SetTarget(targetBitmap);

 ....

 writeFactory->CreateTextFormat(L"Arial", nullptr, DWRITE_FONT_WEIGHT_LIGHT, DWRITE_FONT_STYLE_NORMAL,
 DWRITE_FONT_STRETCH_NORMAL, 32.0f, L"en-US", &textFormatAccountCreds);
 textFormatAccountCreds->SetTextAlignment(DWRITE_TEXT_ALIGNMENT_LEADING);
 textFormatAccountCreds->SetParagraphAlignment(DWRITE_PARAGRAPH_ALIGNMENT_NEAR);

 std::wostringstream outAccountName;
 outAccountName CreateTextLayout(outAccountName.str().c_str(), (UINT32)outAccountName.str().size(), textFormatAccountCreds, (float)800,
 (float)600, &textLayoutAccountName);

 const float color[4] = 1.0f, 0.5f, 0.3f, 1.0f ;
 immediateContext->ClearRenderTargetView(renderTargetView, color);

 d2dDeviceContext->BeginDraw();
 d2dDeviceContext->DrawTextLayout(D2D1::Point2F(2.0f, 5.0f), textLayoutAccountName, blackBrush);
 d2dDeviceContext->EndDraw();

 swapChain->Present(0, 0);

As you can see in the screenshot, the text is rendering very poorly - letters are cut off, etc. I can change the size / position and the rendering issues manifest differently, but they still persist.

What am I missing here? I've been through most of the DirectWrite docs on MSDN and it's not clear what my problem is. I do see some mention that I should specify the starting position of my text relative to the dpi scale, but the example is very vague.

It's also worth mentioning that I'm using Direct3D and DirectWrite with Direct2D all together, in a similar fashion as seen in this tutorial. Not sure if that's causing my problem.

I would be very grateful for any assistance. Thanks much.
