I use R (ports/math/R) to run analysis after some A/B testing,
generating sets of reports, as well as graphs saved as PNG files.
I then use less(1) to view the reports and xv(1) to view the graphs.
(I know that xv is ... not the newest, shiniest piece of software in the
world. But -- until yesterday, anyway -- it has been reliable for me
since before FreeBSD existed.)
Yesterday, the first few images I viewed looked OK, but after I got to a
certain point, xv would claim that the file was "672x672 PNG 24-bit
mode. Using TrueColor visual." -- but display it as a 1x1 blank image
(geometry confirmed by the window manager).
=46rom that point on, all images displayed as 1x1.
But if I switched the sequence around, the first few images I viewed
(which showed as 1x1 earlier) looked OK, up to a certain point,
when the images all reverted to 1x1 again.
I thought that there was a problem with my R code, or with R itself (as
it had recently been updated).... but I reverted the last couple of
changes to math/R and rebuilt it, to no avail.
Then it occcurred to me that I could subvert a Web browser to view the
images... and they were all fine. (I subsequently verified that they
were all OK when viewed with gimp(1).)
So the problem appears to be involving something that is in or used by
xv(1) that is not in or used by firefox or gimp (at least, not in the
way that xv does).
I tried rebuilding graphics/png, also to no avail.
xv looks like:

I rebuild FreeBSD daily, and update installed ports daily; above
was running:
FreeBSD g1-252.catwhisker.org 10.3-STABLE FreeBSD 10.3-STABLE #418 r302600=
M/302639:1003505: Tue Jul 12 04:11:56 PDT 2016 root@g1-252.catwhisker.o=
rg:/common/S1/obj/usr/src/sys/CANARY amd64
My ports are all built under stable/10. I was able to re-create the
symptoms while running stable/11:
FreeBSD g1-252.catwhisker.org 11.0-BETA1 FreeBSD 11.0-BETA1 #40 r302627M/3=
02639:1100120: Tue Jul 12 03:52:24 PDT 2016 root@localhost:/common/S3/o=
bj/usr/src/sys/CANARY amd64
(but using the stable/10 ports -- I have ports/misc/compat-10x installed).
(Above times are PDT -- UTC-0700.)
Anyone else see anything like this, or have suggestions for me to help
diagnose the nature of the problem?
Thanks! I've munged Reply-To to reflect that I do not subscribe
