xf86Rotate, it was delaying unwrapping the BlockHandler until after calling xf86RotateRedisplay. If there was a software cursor on the screen, the redisplay operation would cause cursor to be removed from the frame buffer and the misprite block handler to be inserted into the block handler chain with the misprite screen private saved block handler now set to xf86RotateBlockHandler. When xf86RotateRedisplay returned, xf86RotateBlockHandler would then set screen->BlockHandler to its saved value, call down and then reset screen->BlockHandler to xf86RotateBlockHandler. miSpriteBlockHandler would never be called after that, which meant that the software cursor will now disappear from the screen whenever rendering overlapped and would only reappear when the cursor was moved. To correct this, all that is needed is to move the restoration of screen->BlockHandler to the top of xf86RotateBlockHandler, before the call to xf86RotateRedisplay.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
