Window frame not drawn properly

[sascha.spoerle]

Hello together,
do you have any idea why sometimes the window frame is not drawn properly. Is this a bug or do I have to do a specific setting?

You might have applied a transparent material to the window by mistake. Try to drag and drop any matte material to those "hole" in the wall and see if it helps.
