After the recent update to Openmotif 2.3, items in XmMultiLists are not displayed correctly anymore. This problem did not exist in Openmotif 2.2.3; and also does not show up on a different computer running Openmotif 2.3 on FreeBSD and OpenSolaris, so it's most likely introduced in Gentoo packaging/patches. To reproduce, run the 'ext18list' demo program included with the sources, add a couple of players and try to select some item in the list on the right (if the list becomes partially obscured before selecting another item, things get really interesting). Below is another small test program that demonstrates the faulty behavior.
Created attachment 148163 [details] small program that demonstrated bug
Created attachment 148165 [details] Makefile for above test

Thanks for the test program. Looks like the patch that fixes bug 210220 is responsible for this. Can you comment out the "epatch" line in src_unpack and try if it works properly then?
Should be fixed now (without revision bump).
Issue reappeared in openmotif-2.3.1, reopening.
Fixed (again) in 2.3.1-r1 and verified with the test1 program.
Reported upstream since 2.3.1-1 still has the problem: http://bugs.motifzone.net/show_bug.cgi?id=1453
