White background in library treeview with Linux

[jus]

With current trunk there is this ugly white background in library treeview (see picture). Tested with Gnome 2.3 & Unity 2D on Ubuntu Linux.

Ubuntu 11.04 with KDE 4.6 & MacOSX looks fine, not tested with Windows.

Hmm, i am stumped here.

While transparent background works for QTreeView , i simply can`t get transparent background to work for QTreeView::item & QTreeView::branch in Linux with Gnome2 ( see picture in #1). It works only with solid colors.

Example (around line 131 in Deere`s skin.xml)
Works
QTreeView::item { background: blue;}
QTreeView::branch {background: red;}

Works not (result in white background)
QTreeView::item { background: transparent;}
QTreeView::branch {background: transparent;}

The same is with rgba colors. If you use transparency there , the white background shines trough.
Also tried transparent background images e.g. QTreeView::item { background: url(skin:/style/style_bg_treeview.png).
Nada...

This might be a QT bug?
Any hints?

Which version of Qt is it?

Marking invalid, since the bug is gone now.
Tested with lp:mixxx and Ubuntu Linux 11.10 Gnome Classic and Unity

Reopened since this nasty is still there in distributions using older versions of QT < 4.7.0 as reported in a duplicate report: lp:887528

This is fixed in newer versions of QT, so upgrade if possible.

I think "Invalid" is appropriate here since we're saying it's not a Mixxx bug, but a Qt bug.
