That’s all very true, however, my most important question is: Is anyone working on that issue already or not?

Regarding your suggestions:

·         I don’t think that creating a test for anti-aliasing is feasible. As far as I am concerned, it is disabled in rendering tests on purpose due to the differences of hardware. If there is any reliable way to test it automatically, we already provided a script reproducing the error. The renderwindow can be used against a reference for a rendering test.

·         As far as I know, it’s broken everywhere. As mentioned in previous mails we tested this on Mac, Linux (Ubuntu and Archlinux) and Windows 7.

·         We also found a fix with some “hack” which probably destroys other features. See Mantis for more information.

Bottom line, I think we need feedback from VTK developers to continue.

Regards,
Thomas

Developers of open-source projects often have some freedom in prioritization of their tasks, so actually I think it's a good idea to let developers know that a particular fix is critical for you.

To expedite the process you may also consider:
* creating a test that detects the problem
* running the test on various computers, with different settings and share the results
* asking advice from developers about potential approaches to fix the issue, trying to fix it yourself, then submitting a patch for review

Since this is a major issue for us, I am curious: Should I keep pressuring you here for a fix or in mantis? Or are you already looking into it?

Well, pressuring developers for fixes to an open-source project isn't necessarily a strategy I'd advise ;) But I will be looking into this soon, and plan to have a patch in the next week or two. I'll update the bug report/this thread as things progress.
