Loopmash FX No waveform in the GUI.

No biggie but the loopmash FX in my Cubase 8.5 stays blank in the waveform bit of the gui. All works OK but no moving waveform. Is this a bug or just a quirk of my set-up. Windows 10.

I had this issue with my old machine, it turned out to be the graphics card, I wanted a quieter one anyway which is how I found out what was causing the issue after installing the new one.

Thanks for your reply, sort of suspected this may be the case. My graphics card is getting on a bit.
