*VERY* old [where the *@!&(*@(*@ do all these ancient users come from?
Really, it baffles me.  No updates for four+ years?  Really?]  I
understand lagging for stability and getting-work-done, but... multiple
years?

If it worked previously and now doesn't - it is *not* an Evolution bug
[because your Evolution hasn't changed]. Not creating an X error.  This
is a bug in X, your video driver, Gtk, etc... especially if it
corresponds to scrolling; it is further down the stack than Evolution.
I'd wager some library got updated [gasp!] to a slightly incompatible
version, your video hardware is dying, or the user [admin?] mucked up
the libraries by forcing something or making a 'manual' change.

Do not discount your video hardware dying [or somehow becoming
unstable].  I've twice been able to crash a workstation by doing things
on the screen with particular applications - once because the video card
installed was "not supported" and once because a RAM stick was dying.
Replacing the *physical* components resolved the 'bug'.  Why those
particular actions invoked the doom?  Way above my pay grade,  but I
went to college for Electronics Manufacturing and know enough about the
insanity of bus timing on that scale to have no problem believing it.
