Weird Lighting/Shadowing Artifacts?

[CnS-Contracting]

Hello all,

 

I've been working occasionally with Home Designer Pro for a while now (11 months), and I've noticed that the program quite often renders these weird lighting artifacts.
I was wondering if anyone could shed some knowledge as to why this happens and what can be done about it (if anything). The lights in the image are point-lights, but I've tried every type and each leave a different kind of artifact.

 

Here's the image:

Any advice would be greatly appreciated. Thanks.

I am guess you are talking about the light coloured streaks by the desk and window , I also see white vertical lines at the end by the Lambo. pic are they supposed to be there? 

 

I think you should send the plan to TS so they can look at it , I haven't seen this issue but I don't have the latest version of Pro either.

if you get an answer please update this thread so we all know the possible issues and the fix.
