[CentOS] bad text under KDE and C7

I recently installed C7 from a C7+gnome CD.
Gnome was awful enough that I promptly installed KDE.

KDE is not doing so well either.
Text in text editors invoked by "opening" a file is flakey at best.
E.g. pieces disappear and duplicate.
Terminals seem ok, including vim invoked from the terminal.
Firefox text seems ok.
The sidebar text in file-browser windows often has "black tape" over it,
usually completely covering text.
The file names are ok.

Suggestions on how to dignose this?
