So, this didn't help at all, and just seemt have as effect that when it
goes wrong, it now still seems be responsive for a while, and then give
the error.

What i notice when it works is that the screen is mostly something close
to white, except the top 80 lines.  There is also a white square also
about 80 lines or something lower then where it ends up after it has
properly redrawn it.

When it fails, it already already has the bottom half of the screen, but
about 80 lines lower than it should be, top half is black, except the
top 80 lines or something, which look about the same as when it works.
It then just seems to move everything up 80 lines, and then it hangs.

Just before it hangs, and the top half is black, with the delay that I
changed, I can perfectly move the mouse into that top half and it
properly shows it, but that's probably normal.
