Hello,unfortunately the problem remains the same. I installed with dpkg. It worked fine in the stretch-backports version. I have another problem with this package. The starlanes between producing stars are weirdly cut at the ends but this problem occurred only after I changed gpu and happened in the backports version as well so we can probably rule that out.
