No, the patch did not fix the "rubbish issue", just the segfault.

If this is present even for empty boards, then there aren't many things
that get drawn (cursor, selection, background?) This could be a viable
option.

It is present for all boards I've tested, including blank. It manifests
itself only in the area not occupied by the board, or outside the
drawing area. If I zoom in and the full window is occupied with the
board, I can see no garbage.
