Raspberry Pi Forums

Hi,
I'm new to programming graphics on the Raspberry pi. I've been trying to deconstruct the
samples provided in /opt/vc/src/hello_pi/ directory, I'm using a Rasp Pi 3 model B and I was
wondering why when I run some of the samples that after using them (triangle2 for instance)
they will lose functionality (e.g. no longer respond to mouse input) or freeze altogether.
Is there some state stored that's not loading properly on subsequent runs?

-Thanks

Hello.

I have noticed this also. But I though it was only hello_fft making such problems. Will check later.
For answer maybe someone from foundation can look for it.
