#552 Problems with construction lines

[Frank Storm]

The current librecad snapshot (20151231) has problems with connstruction lines going from the lower left to the upper right. I have attached two screenshots of the same DXF file, one from the latest build and one from an older version which still behaves correctly. The lines are not shown, although they are somehow there, because if I zoom in, they become visible at a certain point. It is also not possible to draw parallel construction lines from lower left to upper right (other direction work fine).
If needed, I can provide the DXF file.

Regards,
Frank
