[TF2] [Linux/OpenGL] Displacements on map cause issues with the rendering-engine making it crash on certain maps.

[Splarkszter]

Description of the issue: When attempting to load certain maps, the game crashes without leaving a crash window pop-up.

This console log mentions issues about qhull; we searched on forums and came to the conclusion that flat-displacements are the cause of the issue since we tested a version of the map with all displacements removed and the game didn't crash.

Displacement details: mvmRAID_woods_v3.bsp
•Displacement brushes: 80.
•Displacement power used in Hammer editor: Power 1 and Power 3
•None of the displacement brushes were sculped or had their geometry modified; all displacements were completely flat.
•Not sure if the crash is affected by textures, but the textures used for all displacement brushes (as seen in Hammer editor Texture browser) are as follows:
  -nature/blenddirtgrass001a
  -nature/blendgroundtograss011_island

OP, does this still happen with the new Vulkan render?

Hello!

Sorry, i don't have access to the map it happened in anymore, it was a map designed by another person and that i participated on bug busting. I'm not a mapper myself :(
