1. A computing system comprising:
a network controller;
a display;
a processor coupled to the network controller and the display; and
a memory including a set of instructions, which when executed by the processor, cause the computing system to:
detect an immediate flip request associated with a current frame of a video signal,
generate a modified frame in response to the immediate flip request, wherein the modified frame is to include, in a transition region, a plurality of scanlines containing transition content associated with the current frame and a successive frame, and
send the modified frame to the display;
wherein to generate the modified frame the instructions, when executed, cause the computing system to:
render the current frame on a first display plane,
render the successive frame on a second display plane, and
vary a relative opaqueness between the first display plane and the second display plane to blend content from the current frame and content from the successive frame using a dithered blend to obtain the transition content,
wherein the dithered blend combines pixels selectively from the current frame and the successive frame according to a predefined formula.
