Machine: Linux 2.4.21-4.ELsmp #1 SMP
When I run
~/qt-x11-commercial-src-4.2.3/examples/widgets/lineedits/lineedits -style plastique
I find the the border color of "lineEdit" widget is different from Qt4.1.3's.
The border is thick black, and look ugly.

Is it really Qt4.2.3 bug?
If yes, how can we fixed?
If no, how can we avoid it ?

The Qt4.2.3 Library configuration option is
configure -static -debug -no-fontconfig -no-xrandr -no-glib -no-iconv

By the way,
The same condition on Solaris machine.
