0.9 stable update, problem persists. Per Unixe, it seems to be related to radar pathing. Will try to recreate and update this reply with results.
Update: now the spectrogram screen doesn't work at all.
Same here. Windows 11 on 0.9.0 on the a090n buildEdit: A workaround has possibly been found by simply putting the path tracker back in and removing it, at least for my case. Try it!
