D1251 D3D State Issue |
66bf3ec9-08e2-4f3e-a883-f81ec70428a9 |
The state of the Direct3D device changed when Direct2D was still using it. This may be indicative of a threading violation because only one thread may use the device at a time. |

The state of the Direct3D device changed when Direct2D was still using it. This may be indicative of a threading violation because only one thread may use the device at a time.
The application may be using a single threaded D2D Factory on two different threads at the same time.
Make sure that the application is properly respecting Direct2D's threading policies.
