Borders were still "easy enough" to guess along the lines: VIC turns on the border when it reaches the end of the 25th row. It doesn't turn it on when passing through the end of 24th. But if I switch it to 24 rows right after the 24th is already rendered, then it may "think" that the border is already on and skip turning it once more. Then horizontal borders were a natural extrapolation of the same thougts. But for some of the newer effects I couldn't find convincing story to say to oneself as explanation how it could be guessed.
