Thanks a lot Xerxes, I was supspecting something along these lines. I have both AMD and NVIDIA cards, the former is used for OpenCL and the latter for OpenGL (connected to a monitor). It it thus intended to have both drivers and it worked flawlessly in the previous Mint. Now, in the current system, I can in fact use OpenCL with AMD and any OpenGL app I tried works with NVIDIA, except for the JOGL-based viewer in question.

I guess it is rare that there are cards from two vendors and thus someone decided that it is easier just not to support the combination. For me, it is surprising as I would thought that a driver in a 2017 Linux is something so modular that it has no problems with a separate driver of a separate device.

But it is as it is, and thus I guess I should remove AMD OpenGL drivers without removing AMD's OpenCL functionality. I will try and tell you if it worked, in case anyone has a similar problem and stumps into this forum.
