screen capture of a fouled IO Plot

Build Information:
Version 1.8.7 (SVN Rev 49382 from /trunk-1.8)
--
in the IO Graphs window, I have 5 plot lines configured:

L1: (unfiltered)
L2: cpha or edp or browser or bootp
L3: arp
L4: tcp
L5: icmp

The displayed plot is fine.
As I move from file to file in a fileset (10 MB/file, typically < 90k frames
for spans less than 1 hour,) however, the span of the x axis is incomplete. 
Originally, I have to scroll right/left to see the whole plot.  In the example
I have before me now:
1st time in capture = 12:45:53
Last time in capture = 13:22:28  (frame # 87640)
IO Graph x-axis displays 12:45:53 to a little after 12:47:33 (I'll attach a
screen capture)

When this happens, I change the tick interval (10 minutes/tick,) let it replot,
an then go back to the original tick interval (1 second/tick,) and all is well.
So, unless there's some kind of leak or corruption, this issue seems a user
annoyance than a big deal.
This problem reproduces easily for me.

Other settings on the IO Graph window:
- X Axis
--- pixels per tick = 1
--- view as time of day:  checked
- Y Axis
--- packets/tick (or bytes/tick - I've seen it with both settings active)
--- scale:  auto
--- smooth:  no filter
