(WIP) Minipuzzles 3 - The Late One
Did you place cube map sample points in the map? That usually reduces this effect, although it doesn't seem to go away completely, especially on glass textures.
Remember to run "buildcubemaps" in the game after compiling.
(By the way, the second image with all the light beams looks cool!)

Of course I have cubemaps and builded 'em in hdr and ldr, otherwise I cant get any kind of reflection...
OK great!
Anyway, the edges of the 6 images of a cube map never seem to match up seamlessly. In cases where this effect is really obvious and annoying, you might try to move the sample points around a bit, or change the cube map texture resolution.
(I have once taken the rather radical approach of binding a glass surface to an env_cubemap contained in a black box outside the map, because I couldn't get rid of those seams. This is not ideal of course, as it disables reflection for that surface.)

double post 
to be honest, double posts are ok here (mostly)
better than no posts 
lol. this forum = 
it's normally active.
much moe than MAL 
Seriously, what do you guys expect. Portal is about 2 years old, with no updates or official addons or anything for it. I'm frankly surprised that there's this level of activity still. Most people move on for a game after a year or so, when it's effectively dead to the developers.
