Display error when using top with the memory bar or block graph

[Chris]

Most of the time when using top in the display mode with a memory bar or block graph (by pressing "m" in top), the graph exceeds the scale by far and also the displayed number for memory usage is not correct. In the usual "numbers only" view the numbers are correct.
I was not able to figure out when this problem appears or not, but it appears most of the times for me.
I attached a screenshot to illustrate the problem.

For some reason the problem seems to be solved in Ubuntu 18.04.
