I found my problem regarding the systray being _completely_ unreadable. Some time ago, I had manually added "Option "MigrationHeuristics" "greedy"" in my xorg.conf to fix another problem. Removing this line has made the kde4 systray work as for everybody else, i.e. with icons rendered right, but background filled with garbage.
