<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">To be more aggressive: DO NOT DO THAT! NEVER!
Qt::transparent is Qt::black with zero alpha component, so whenever someone (UI Styles) test the the background color, they will get rubbish for this widget (unless you check the alpha component and conditionally treat this as invisible)
This approach showed up someone in the early KDE4 days and is since then the pestilence in visual KDE code (so eg. bespin during polishment tests widgets for doing this and tries to fix them up as good as possible)
use ::setAutoFillBackground(false) on ::viewport() but please DO NOT FREAK THE PALETTE, seriously ;-)
Another issue in this regard are several QItemViews, because they operate on hardcoded QPalette::Text, so if you want to make such view "transparent" you should not only viewport()->setAutoFillBackground(false) but also (and actually) will unfortunately have to "fix" the palette by aligning palette().color(QPalette::Text) and parentWidget().palette().color(QPalette::Window) - that includes filtering QEvent::Application/PaletteChange and re-fix the colors under this incident (smart approach is to check whether the color is already correct and not trigger another PaletteChange event in that case ;-)
For the very same manner, please do not abuse setStyleSheet() for being lazy to correct colors (now actually changing the palette, maybe even better: set[Back|Fore]groundRole()) - you'll end up with hardcoded colors (even if you select them at runtime) bypassing the style, and in 90% of all cases will break bright on dark palettes.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I'm not surprised.
It happens so often and happens so often "wrong", that there should ideally be a (static, but we'll need an eventfilter) helper function to do that (like static KStyle::makeTransparent(QAbstractScrollArea*), but i'm unsure about the "proper" class/namespace) in frameworks or so - and how to make ppl. use it.</pre>
