Abstract
A non-blocking always visible display application is provided to copy and save first pixel values corresponding to a first display screen area, blend the copied first pixel values with second pixel values corresponding to a non-blocking always visible display to generate third pixel values, and replace the original first pixel values with the third pixel values to effectuate display of the non-blocking always visible display. In one embodiment, the application further monitors for display operations that impact the first display screen area, and re-blend accordingly. In one embodiment, the re-blending and replacement are advantageously delayed. In another embodiment, the application further intercepts and causes cursor events to be handled properly, based at least in part on a current blending bias between the non-blocking always visible display, and the underlying display windows.
