3.3.5.2.2 Processing of the Offscreen Bitmap Cache Error PDU

The structure and fields of the Offscreen Bitmap Cache Error PDU are specified in section 2.2.2.3.2, and the techniques described in [MS-RDPBCGR] section 3.3.5.2 demonstrate how to process the contents of the PDU.

Once this PDU has been processed, the server MUST disable offscreen bitmap caching for the duration of the connection and resend the graphics data associated with the affected area.

Once offscreen bitmap caching has been disabled, the server MUST NOT send the Create Offscreen Bitmap Alternate Secondary Drawing Order (see section 2.2.2.2.1.3.2) for the duration of the connection.
