Hi Stranger,
If I'm interpreting the bug report and your experiences correctly, this
all stems from the following, which was the culmination of several
previous commits. The commit message acknowledges the behavior I think
you're experiencing.
commit dedaf6e1a81738ff08ee8e8523871e12f555ad6d
You see, I used to have a buddy over in the Czech Republic and he
insisted on two requirements: 1) preserve the user's context even when
signaled; 2) reduce SIGWINCH impact under some distros.
We began a lengthy series of posts around this time.

Unless I'm mistaken, when exiting top the only time there is display
"corruption" is when one has resized the terminal after starting top.
And for that you must thank your terminal emulator.
Are we good?
Regards,
Jim
