Screen corruption with ncurses-6 snapshots since 20170729

[Chris Clayton]

Hi,

I have ncurses-6 installed and update to that latest snapshot from time to 
time. Today I updated to the 21070826
snapshot and found that I get some screen corruption when using the kernel's 
'make menuconfig' command. The latest
version that doesn't produce the corruption is 20170722.

My terminal is mate-terminal-1.18.1 with the character encoding set to "Current 
Locale (UTF8)". The output from the
locale command shows:

LANG=en_GB.utf8
LC_CTYPE="en_GB.utf8"
LC_NUMERIC="en_GB.utf8"
LC_TIME="en_GB.utf8"
LC_COLLATE="en_GB.utf8"
LC_MONETARY="en_GB.utf8"
LC_MESSAGES="en_GB.utf8"
LC_PAPER="en_GB.utf8"
LC_NAME="en_GB.utf8"
LC_ADDRESS="en_GB.utf8"
LC_TELEPHONE="en_GB.utf8"
LC_MEASUREMENT="en_GB.utf8"
LC_IDENTIFICATION="en_GB.utf8"
LC_ALL=

The corruption can also, however, be seen in xterm-330.

The corruption can be viewed by running 'make menuconfig' in the directory 
containing the linux kernel source. Navigate
to Device-Drivers-->Input Device Support-->Horizontal screen resolution. I have 
a (.png) screen dump if that would help.

Let me know if I can provide any additional diagnostics.
