statusbarmessagelabel.cpp #46
QPalette palette;
palette.setColor(QPalette::Background, Qt::transparent);
setPalette(palette);
is probably redundant, as widgets are transparent anyway 'nowerdays
(looks like Qt3 ported code ;-)

but:

sidebartreeview.cpp, #49
QPalette palette = viewport()->palette();
palette.setColor(viewport()->backgroundRole(), Qt::transparent);
viewport()->setPalette(palette);

this seems to be a common problem:
it triggers problems if QPalette::Text does not contrast QPalette::Window 
(the new effective bg color), so you probably want to
palette.setColor(QPalette::*, QPalette::Text 
palette.color(QPalette::*, QPalette::WindowText));
* = Active, Inactive, Disabled

+++ AND +++ for some reason (Qt?!) it seems as if the corrected palette needs 
to be applied to the scrollarea, NOT the viewport (i.e. does not work then)

in general it may be a "more proper" way to set
palette.setColor(viewport()->backgroundRole(), palette.color(QPalette::*, 
QPalette::Window));
and in addition
viewport()->setAutofillBackground(false);
to keep an idea of what the widget looks like
(still needs to be applied on the scrollarea, adjusting the 
background/foreground roles does NOT work - due to Qt for sure this time)
