This ticket did not get assigned/cc'ed to maintainers.

This looks like a possible upstream issue:

GRC (or python scripts) crash on any flowgraph with the gr-fosphor block, so something even this simple will do: attachment:test.grc

This should be Qt explanation

Are you using Qt 5.14? If so, the rendering is not on the main thread and we need to wait the osmocom team. Maybe send the issue on the mailing list.

Yes, and correct. The rendering ls clearly not on the main thread.
