It looks like the transparency of the objects is rendered to the screen. Could you try Canvas::SetPixelWriteMode( COLOR_ONLY ) before drawing the stuff to the screen? If that doesn't work, draw the lense with the COPY_BLENDER.

With Canvas::SetPixelWriteMode( COLOR_ONLY ) the lens simply doesn't draw
COPY_BLENDER works perfectly thought :)

One last thing there is the fix is the corruption of the lens when the mouse pointer is too near the screen edges and tris to CopyFromScreen from outside the screen

Can't you just not try to copy stuff from outside the screen?

How would you do it?
CopyFromScreen doesn't have width and height paramenters

Yeah, that's right. Well, I could make it to clip to the screen automatically.
