Whenever I zoom in/out in the archicad screen, every fill just dissapears (including wall cut fills, slabs, etc.) turnning into transparent fills and it just stays like that.. its very annoying.
when i draw another wall, all the fills return; however, if i zoom in/out or pan the screen, it happens again making it hard to work.
