After successful building of the software I was able to start the oszilloscope and reproduce the error which I found on the precompiled package too:
For some actions/button togglings there seems to be a notification window. I don't know when this exactly happens, but if it happens the program freezes and I find the following message on the shell (when launching from the shell):
(sfScope64r:99869): Gtk-WARNING **: 22:05:02.729: Negative content height -11 (allocation 1, extents 6x6) while allocating gadget (node button, owner GtkButton)
After that I have to kill all processes and unplug the hardware for a clean restart. That's no way of work!
Who can review this bug? Which input shall I deliver?
