Hello

At first, we only maintain the very latest version, which is currently JOGL 2.3.2. We won't backport any bug fix into an older version. I don't remember a bug report about multi sampling but don't take the risk of wasting time on a bug we have already fixed. I won't investigate any further if you stick to an obsolete version.

I can't help you without seeing the whole source code, please post a SSCCE.

I advise you to look at our unit tests and to run your code by using different canvases in order to eliminate some possible root causes. For example, if you already use a GLJPanel, try to disable the vertical flip and the build-in GLSL shader first, then try to run your code with GLCanvas or GLWindow.

By the way, I advise you to use a FBO:
