When I don't create any portal, the image is ok.
However when I create the portals I have walls that become transparents and the image inside one of the portal is not correct.
The picture I include show it.
I'm using an intel hd4000 under Kubuntu 12.10
Note: I have an other issue, the steam overlay in portal didn't work for me today though it worked before.
We’re looking after all the intel driver issues here https://github.com/ValveSoftware/Source-1-Games/issues/390 so closing as a duplicate, please make sure your mesa is up to date aswell!
