> which may avoid tearing (though I don't see why) What I meant here is that I didn't see why asynchronous updates may introduce tearing; but my tired brain couldn't quite formulate it properly. And to answer that, it's clear to me know that an update of the pointer position while the pointer sprite is being drawn would introduce a shift somewhere within that sprite, which is, I suppose, the tearing discussed (and not a whole frame tearing). > I don't know however if the mouse pointer picture is still handled the VESA way, or if GPUs video cards nowadays have a more generic API, or what. Also, the VESA interface doesn't seem to handle mouse pointers, it's something that was available in the VGA BIOS, to provide a uniform support for this feature, as each vendor most likely did it their own way.
