Black and white cursor on qt5

[RazZziel]

I'm using this code to replace the cursor on my Qt application:

QApplication a;
a.setOverrideCursor(QCursor(QPixmap(":/pixmaps/circle.png")));

On Qt 4.8.6, the cursor looks perfectly fine, preserving all the colors (original circle.png: http://i.imgur.com/HHzJJJA.png)
On Qt 5.4.0 though, the cursor looks black and white (screenshot: http://i.imgur.com/cAf24Zv.png?1)

Is this a bug in Qt5? Is there any way to workaround it?

Which OS/Platform are you using?

@mcosta Woops, forgot that bit

I'm reproducing the problem in Archlinux/X11/KDE.

I just checked on Ubuntu/X11/Gnome3, Ubuntu/X11/XFCE and Windows 7, and it works correctly there, so the problem must be specific to my setup.

I'm having the same issue, also on Arch, Qt 5.4, on GNOME 3. Did you find any way around this...?
