[gentoo-user] jagged, grey, fine, horizontal lines on xterm border

[7v5w7go9ub0o]

Just upgraded to xorg-server-1.5.3-r5, and now I see some sort of
pattern on the edge of my xterms; reminiscent of the gray background of
basic xwindows.

I seem to recall seeing this years ago, and having to modify a
configuration somewhere (e.g. with "solid" or "black" or ??). Can't
remember if it was a fluxbox configuration, .Xdefaults, XDM, Xorg, or
.........

Would love to see this go away..... any ideas, please?

TIA
