I get this error when hit esc after previewing a sketch. should I be worried about that? Thanks

Found this. Are you using Eclipse or another IDE besides the Processing IDE?

Yes. I use Atom mostly for Ruby and Javascript development.

Oh but - I’m not using Atom when I’m coding in Processing. I’m using the IDE.

It looks like an error that’s coming from the opengl library Processing is built on. What operating system are you using?

it is => ubuntu 18.04.1

So chances are Processing can’t find the jogl library. I honestly don’t know enough to give you any useful instructions. My guess would be that either it can’t find the right jar or the jar it did find doesn’t work on ubuntu. From what I can tell there are a couple included versions of jogl for linux.
Hopefully someone else can be more helpful. Best of luck.

i get this error too, on processing ide under raspberry pi. Did you solve this?

I think I’ve had that for years. Maybe we could make a t-shirt with that message, to be constructive :slight_smile:
