I am trying to build an application representing a led matrix (or many of them) which are going to reakt on musik and flash the leds in sync with it.
My gui looks like this:
But after I play a song for a while, flashing the "leds" I get dead pixels like this:
The longer I play, the more dead pixels I get. In my log I am getting this exception:

My code can be found on GITHUB and here bellow. If you like the music played from your computer to the input of your computer (so you can get it from the code) you need to enable "Stereo Mix" on your soundcard if you have that feature, I needed new drivers to make it work. Othervise you can just play music in a microphone.

Please be nice to me, this is my first Java FX application and I am not that experienced with desktop guis.
Can anyone point me in the right direction, how can I make this work?
Let me know if there is anything I can do to help you help me.
