When trying to execute the Tulip 5.7.3 AppImage on Ubuntu 22.04, it directly crashes, see below.

Segmentation fault (core dumped)

The crash occurs in the Intel Iris graphics driver when it calls the _glapi_add_dispatch function from libglapi.so bundled in the AppImage.

To fix that issue libglapi.so should be removed from the AppImage bundle, tested by extracting the AppImage and removing the bogus shared library.

Intel GPUs are quite common nowadays so I guess I am not the only user affected by that issue.

[Antoine Lambert]

To be noted, the crash occurs with the upstream version of the Intel drivers installed from a PPA, reverting back to the default one bundled by Ubuntu makes the crash goes away.

Nevertheless, the libglapi.so should still be removed from the AppImage in order to use the one from the host system instead and avoid this crash on future Ubuntu releases.

Thanks you very much for your report.
libglapi.so will be removed from the AppImage since it seems to be a specific dependency only induced by the local context of the tulip_perspective build.
