I was testing this on GNOME Wayland, so I tried logging into GNOME Xorg and the issue disappeared (but I still get `connect failed: No such file or directory`). I thought this could be something with XWayland, but xprop tells me that freecad is not running under xwayland. I found an upstream issue https://tracker.freecadweb.org/view.php?id=4354 which mentions that it will be fixed with a new version (not yet released) of coin3d, so my issue is an upstream one. > What buttons exactly do you click, in which sequence? 1. open freecad 2. click on the icon "Create a new empty document" on top left
