Thanks for the answer, Valdis. According to the 'xdpyinfo'
output, the GXT2000P
only supports 8 and 24 bit colorplanes (see attached file below). But it's not
quite clear to me what's the conclusion of this: If the 16 bit visuals are the
issue in the GXT255P and the GXT2000P doesn't support them - shouldn't I have no
problem with the icons when using the latter card? (Ok, very naive approach, but
please correct me if I'm on the wrong way here.)
With regard to the splash screen: I see the same logo on b27 and b11, but the
cycling text was introduced in b13 IIRC (excerpt from the announcement mail on
to 21.2.13 "Demeter"
-- Build fixes from Martin Buchholz
-- experimental splash screen rewrite from Didier Verna <<<
-- Various patches from Jan Vroonhof and Andy Piper
-- alist.el synched up with APEL 9.13 from MORIOKA Tomohiko
-- MS Window build fixes from Jonathan Harris
-- UCS-4/UTF-8 support from MORIOKA Tomohiko
Maybe this is causing the colormap trouble, although I can not imagine why, as
the splash screen by default only contains black, blue and red text. Perhaps a
redisplay problem? I'm no expert with this stuff ... ;-)
What I will do, is trying to re-build b12 and b13 and see if my icon problem is
associated with this version change.

Damn. Well, I guess I won't ask my boss to buy me one then ;)
Just as a quick test - does the gtx2000 support 16-bit colorplanes?
You can just do a 'xdpyinfo' and see. The ancient GT4x I have in my
home RS6K only has 8 and 24 bit visuals, the gtx255 has 8, 16, and 24.
I'm suspecting the 16-bit visuals may be the issue (but can't prove it

The issue is probably the order colors are allocated in. I'm willing to bet
that somewhere around -b12 throughh -b19, something else got changed (when
did we add the fancy new splash screen logo?) which caused the card to
screw up the colormap when it ran out.

For what it's worth, Netscape 4.05 through 4.7 and all Tk/Tcl since 7.6 or
so have the same problems getting colors right on a GTX255.
I've been hacking at Exmh the last few days, and I'm sufficiently pissed off
at Tk/Tcl botching it that I'm going to go use a can opener on the Tk source
and see if I can figure out what's going on. Film at 11. ;)
