I'm confident the issue is not my code, as this problem occurs also with the examples included with the most recent version of Syphon for Processing. My code is using Syphon for Processing, v2.0-RC2 to read with Syphon Recorder http://v002.info/forums/topic/syphon-server-in-processing-3-not-working/ (13), though I have also tried reading Syphon with Max 6, with the same problem happening. Below you will find the messages pertaining to Syphon that I get on Console. The image I receive in Syphon Recorder seems not to be from the sketch I'm running but a chopped version of the Processing coding window. The same thing happens both with my code and with the provided examples. I will also attach a screen capture from Syphon Recorder so you can see what I'm getting.

Processing uses OpenGL for 3D programming. Whenever I run the program on my computer, everything works perfectly, but whenever my one friend runs it on his computer, he gets an error saying OpenGL error 1282 at bot endDraw(): invalid operation. Since the problem is isolated to a single computer, I am convinced that it has nothing to do with our code. My friend is running Windows 7 x64 on a Dell Inspiron that they got about three years a go. Just to give a comparison, I am running Windows 8.1 Pro x64 on an HP ProBook 4540s that I got last summer. We are both running the latest version of Java 8. My friend has tried updating his graphics card drivers as suggested on this page, but nothing has helped.

This sounds like the hardware does not support the OpenGL version the code is written against. –Ramhound Apr 4 '14 at 22:02 @Ramhou
