Hi.
I’m working on Salto (the simulator for the Xerox Alto) which uses SDL
to emulate the bitmap display and mouse on the Alto.
I’m seeing the following issue: when I don’t update the coordinates of
the cursor, I still see in cursor bobbing up and down by a few pixels…
occasionally by a hundred pixels or so.
Not sure why.
At first I thought this was a side-effect of the “SDL_ShowCursor() warp
cursor” feature described by Zoltan here:

I’m running SDL-1.2.13-11.fc12.x86_64 on Fedora 12, a Phenom box (x86_64).
I’ll try building on MacOS (if possible) and see if the problem exists
there, too.
