Hello Colin, thanks for the explanation and report! Ideally, PYQTGRAPH_QT_LIB can be exported just to make sure the right backend is used.
However I'm adding the new runtime dependency, to fix tests and reverse-dependencies. In the future I think upstream will drop qt5 and pyside2, simplifying a lot the dependencies needed. G.

The complication is that which exact packages are needed depends on the Python Qt bindings you're using, of which pyqtgraph supports several. Should asammdf just deal with this with a new Build-Depends (if so, please reassign back to src:asammdf), or should something change in pyqtgraph? I don't know this area well enough to make a judgement call. Thanks, -- Colin Watson (he/him) [[email protected]]
