[ooops . . . Hit send too soon. Forgot the primary recipient. Sorta
important.]
There is a bug in xv 3.10a that causes it not to refresh properly with recent
releases of XFree86 and FreeBSD. (Eg, it started getting really bad when I
upgraded to FreeBSD 4.6 and XFree86 4.2.)
The attached patch will fix it up.
I have submitted this patch to the xv folks but since 3.10a is nearly a decade
old, I think that it would be good to incorporate this patch into the port
patch-set as well.
If this is not the right way to make this happen, please let me know.
The patch is attached. (It wraps if I try to put it in-line.)
This is actually a patch to the xv.c file as patched by the current FreeBSD
patchset rather than as patched from the original xv.c file. If the patch
should be against the original xv.c file let me know and I can readily
generate that patch, but I think it'll probably apply just fine either way.
