Silkscreen geometry imported from DXF collapses upon saving footprint

Software
1

Hi! I’m having trouble with footprint editor.
I sketched the outline of the footprint in FreeCAD, saved it as DXF, and imported into KiCad as B.Silkscreen… After a bit of fight, I got it where I wanted. Placed pads, figured out how to change them…

All done, I saved. Then reopened, to find out that silkscreen geometry that I imported is gone. The pads are still in place.

Well, maybe I did it wrong, I thought… Re-imported the dxf, saved, opened - OUCH! no silkscreen yet again.

So I looked into the file, and found out that the geometry is still there! Just it’s collapsed into zero.

Looks like a bug to me.
I tried attaching the .dxf file here, with no success. I get a message, that new users can’t attach files.
Here are screenshots before and after:

Hi @DeepSOIC
this is a bug in the Legacy Canvas of kiCad 4.06 (F9)

If you use the GAL canvas you shouldn’t have problems (F11)
QP10-6-GAL.kicad_mod (1.3 KB)

this bug is not present on development release also using Legacy canvas

Thanks, Maurice!
Using OpenGL viewer helps! However, only in legacy (“Default”) viewer I can use touchscreen to pan. So I’m considering switching to development version.

Oh, by the way, I totally forgot. I have switched to development version, and it’s all working fine in legacy viewer now!
