D1203: CopyFromBitmap With Multisampled Source
CopyFromBitmap was used with a multisampled source bitmap. The call will still be issued, but the copied result will may not represent the multisample pattern expected.
Possible Causes
The application interoperated a multisampled Direct3D texture as a Direct2D bitmap, and called CopyFromBitmap on the bitmap.
Possible Fixes
Avoid interoperating multisampled textures as bitmaps if CopyFromBitmap functionality is important. The copied result may not represent the multisample pattern expected.
