Walls and slabs (and sometimes Roofs) are disappearing from 3d

[Adam_Weiss]

Hi community.  There seems to be a bug (memory leak?) thats causing certain elements to not show up in 3D views.  The elements are showing in plan and elevation just fine.  They are on the correct layers and phase (same as they've always been.). I've had this problem before with a roof, but I restarted and it resolved.  But now it's back with walls and slabs, and did not resolve itself with a restart.

I think it might be due to having too small a graphics card since I've been using Archicad concurrent with Twinmotion when this happens.

Anyone know how I can fix this?

There can be various reasons for this:
