MILERR_MAX_TEXTURE_SIZE_EXCEEDED

MILERR_MAX_TEXTURE_SIZE_EXCEEDED is a Windows Media Integration Layer (MIL) HRESULT. It indicates that the DirectX surface requested by MIL is larger than the maximum texture size supported by the active device.

What to check

  • Check the requested pixel dimensions after DPI scaling and compare them with the adapter texture limits.
  • Tile, downscale, or otherwise reduce oversized render targets rather than allocating a single giant surface.
  • Recreate the surface after monitor or window-size changes so stale dimensions are not reused.
