Now, in case when mouse hovering hapens just after a SinglePar update

Not completely, but thanks a lot anyway.

are vi.y1 and vi.y2 wrong for some reason?

So, why the NoUpdate flag if the background is to be repainted? And then, if NoUpdate still repaints the background, why do we have the grey areas bug,

You can issue redrawing from vi.y1 to vi.y2, e.g. the upper and lower line of a paragraph, with update_strategy set the NoUpdate. With the old behavior in this case the paragraph was redrawn correctly, but then _all the remaining part_ of the screen was painted grey. Hence the grey bars in certain cases.
