Where did you take instagraph? I cannot find it in official repos nor in AUR.
Maybe you need to rebuilt it, since such utility itself is giving you more errors.
The warning message of xapp is already fixed in upstream: your utility seems to have different issues.
The project is open source and I was able to compile it however it have incomplete “make install” instructions and don’t run anyway because it seeking Ubuntu components, it show only a blank window
$ ./Instagraph

This because not every developer can track the issues with private messages; also because, if someone else is facing an issue, can join in the ticket.
Is the same for every github and gitlab project, as well for every software projects - like, eg, TOR - which have the bug tracker.
