Hi Hugo,

You miss my point I think.  Applications might not work properly under
KDE with Oxygen (which is the default setup on many popular KDE
distributions) if Oxygen does overly unexpected things to widgets.
This might be a small visual glitch in the best case or an application
crash in the worst case - making it unusable.  In that case it will
'work better' on Windows etc. just by virtue of working at all.
Changing the style for a single application is not an easy thing to

Some technically savvy users might know how to change the style for a
particular application that is broken by it, in which case they are
still suffering because the application looks non-native.  Everyone
else will use a different program or more likely a web app which will
look and work the same on all platforms (or at least if it does fail,
will probably do so more gracefully)
