I initially thought this was about left-half vs right-half of the
terminal, but I found that the tearing line is actually fixed with
respect to my monitor -- maximizing the window shows three different
tearing sections, roughly spaced at 1/3 intervals on the screen. The
left and right segments act the same, the center segment acts
differently.
Thanks

Title:
terminal scrolls by updating different regions out-of-sync
Status in “rxvt-unicode” package in Ubuntu:
New
Bug description:
urxvt's scrolling behaviour has changed after upgrading to trusty.
Between precise and saucy, scrolling a line at a time in mutt (holding
down enter) or less (also holding down enter) was smooth and easy on
the eyes. In trusty, however, such scrolling is distracting because
different portions of the terminal update at different rates or at
different times. The effect is very 'bouncy'.
Probably the easiest way to see the issue:
Start a urxvt instance
Maximize the urxvt
Run the following command
paste /var/log/syslog /var/log/syslog /var/log/syslog | less
Hold down <enter> to scroll through the content on screen. See if any areas update oddly or otherwise bounce or vibrate.
Compare the scrolling against xterm; on my system, xterm scrolls as
expected. Compare against scrolling with the wheel mouse or two-finger
touch-pad scrolling; on my system, this scrolling is smooth and works
as expected.
Thanks
