Hi Martijn, Can you please use a file sink to record the signal, so that you can verify that it's different when visualized with Qt and Wx?
Because: there might be a scaling difference between Qt and Wx GUI, but the math should really be the same inside. I'd hence assume that there's really a different signal causing the different pictures. Just to pull one tooth right away: staying with WX will force you to stay on GNU Radio release 3.7 forever, and within that, using a component that nobody in the GNU Radio developer community knows how to maintain. So, I'd still really recommend moving away from WX.
