Hi Tobi,

interesting project, thank you.
In case your org has a budget, please consider <https://forum.jogamp.org/Call-for-funding-and-contractual-work-tp4042741p4043281.html> .. shameless, but a necessity.
Great that the 2.5.0 release was also helping your project.

So from my gut feelings this looks like a data-race condition with (as you also investigated)
with the buffer updates (swap, copy, ..). An occasional 'glFinish()' here-and-there
in your data-feed code may help locate the missing sync? Of course, this would need
to be properly addressed later on.

The background is not cleared and even the content is mangled plus duplication
and wrong transformation.

Aside from the root cause, I would attempt to use a simple GLAutoDrawable w/o FBO first,
i.e. GLWindow or our AWT GLCanvas.
GLJPanel perhaps with disabled GLSL shader: '-Djogl.gljpanel.noglsl=true'.

If anyhow possible, please extract a small application exposing the issue.
Having something more compact to read with less dependencies etc
surely lowers the bar to have a look at it.
You could also use synthetic texture data (assuming the objects are life fed) etc etc.

Yes, handling OSX is some work indeed as they change their API every other release.
Another current incompatibility seems to have appeared w/ 14.4 .. also on the pile
to find a sponsor - a big task in general to keep the project alive these days :-/
