Start up QCAD, *do not pan or change zoom level*. Draw a Ray or an XLine so that it (its extension, in case of Ray) goes through (0,0) and is 45 degrees (ie. draw y = x).
In this case and this case only, the Ray/XLine will be reduced to a line segment exactly between its start- and end points. It seems that this is only a visual artifact: if you pan or zoom now, the segment will be restored to what it’s supposed to be.
If you change zoom/pan back to what it was at startup, the artifact re-manifests itself.
Some flashes indicate that there are some other positions, not just the initial view, that also bring this up (ie. if you pan to a specific position, artifact appears again; it’s probably deterministic, too, but I can’t seem to be able to stop at that exact point while panning so I could count or something).
