You should be able to accomplish the same
effect by allocating a window with allocwindow
for each layer.  Have a look at /sys/src/libdraw/menuhit.c
for one example, or at rio for a more complicated
but perhaps clearer example.  Then the kernel will handle the layers
and you should see the performance you expect.
