Somebody in the thread at some point said:

|  * When we enable or diable the cursor we always do some voodoo loop
| before that, which looks like a wait for the current scanline to be
| far enough from the cursor, which kind of makes sense.

Some undocumented workaround :-O

| The patch still leaves the hw cursor disabled because I can't find out
| why the leftmost column of pixels is blinking together with the
| unmasked part of the cursor, no matter what mask is set.  It seems as
| if the glamo ignores the first pixel of every row of the mask.  I
| spent the last couple of hours on this and couldn't figure it out.

More of the same undocumented features I should think.

Stuck it into andy branch and enjoyed reading about the puzzles.
