[Solved] Weird skybox error

[The_Gl!tch.exe]

Hello there,
I've recently added a skybox area to my map and since then everything went a bit weird. The 3D-skybox only contains the sky_camera entity, light_environment and a disabled func_brush which gets enabled with a button.
However soon after adding I ran into multiple problems.
1. The light_environment was "gone". I fixed this by putting the sky_camera to the ceiling of the skybox area.
2. The skybox textures are flickering. I have no idea what causes this.
3. The map has separate areas having 2D-skybox textures. Those have even more heavy flickering.
4. The skybox room doesn't appear on the map, but the func_brush appears on the map skybox texture when it's enabled.
5. The map has no leak (I already checked the log), but the flickering skybox texture areas are like leak textures when the player starts looking down.
Is it possible to fix this? Or is it a sign that the map is too big?

Can you post your compile log please?

It turned out that the skybox was a little bit smaller than it was supposed to be and that caused the leak appearance on the skybox textures.
Apparently 2D-skybox textures were affected as well.
