Original Pull Request: https://github.com/microsoft/terminal/pull/17193

State: closed
Merged: Yes

This fixes:

  • HRESULTs not being shown as unsigned hex
  • D2DERR_RECREATE_TARGET not being handled
  • 4 calls not checking their HRESULT return
    Out of the 4 only CreateCompatibleRenderTarget will throw in
    practice, however it throws D2DERR_RECREATE_TARGET which is common.
    Without this error handling, AtlasEngine may crash.

Validation Steps Performed

  • Set Graphics API to Direct2D
  • Use DXGIAdapterRemovalSupportTest.exe to trigger
    D2DERR_RECREATE_TARGET
  • No error message is shown ✅
  • If the D2DERR_RECREATE_TARGET handling is removed, the application
    never crashes due to cursorRenderTarget being nullptr ✅
