Revit 2017 windows in 3D... light?

[Anonymous]

Hello everybody, I've been working on a project in Revit 2017 on Windows 10. 

I've been collaborating in a group on this project, and I have a problem:

No idea what's going on here. 

It happened in my elevation views as well, some of those weird beams disappeared when I deleted the windows, but never gone entirely. This makes me think that perhaps I have some kind of lighting option selected but....? I've never seen anything like this before. 

Would be grateful for a hand. 🙂 Cheers

These are typical graphics card artifacts.For some reason your graphics card does not know how to correctly display the data on screen.

Try to disable hardware acceleration in Revit Options. Also look at updating/changing graphics card drivers.

Further llok at other updates (e.g. Windows Revit).

 disabling hardware acceleration didn't work, so I'm updating the graphics card now. hopefully it works. thanks a bunch 🙂
