Display corruption with certain programs

[Andreas Reis]

Ever since switching to ncurses 5.9-dev some months ago I have been 
noticing the same display bugs in "my" applications which use it, htop 
and ncmpcpp. This happens on both my computers. See the screenshots:

The occurrence is not entirely consistent, sometimes htop will look fine 
directly after start. In ncmpcpp it almost always happens, especially 
after a few songs with the playlist open.

Manually selecting a line will "reset" it to proper display, letting the 
program display something else (eg another ncmpcpp menu - which will 
leave the status bar corrupted, as it's not switched) or changing 
console dimensions brings back the proper one, too.
