Bug: (DX11) Model translucency darkening

[tmob03]

Describe the bug

From certain angles, the prop models/props_c17/door02_double.mdl has dark pop-in on the translucent parts in DX11 mode. The vmt is:

"vertexlitGeneric"
{
    "$basetexture" "models/props_c17/door02a_skin2"
    "$surfaceprop" "wood"
    "%keywords" "c17downtown"
    "$envmap" "env_cubemap"
    "$envmapmask" "models/props_c17/door02a_skin2_mask"
    "$envmapcontrast" .1
    "$envmapsaturation" .2
    "$envmaptint" "[ 0.75 0.75 0.75 ]"
    "$translucent" 1
}

Also it seems the lines going through the translucent part are not showing up on the texture in P2CE Comparison: https://user-images.githubusercontent.com/33987871/210919949-2b11a594-be20-4025-9c8e-6aef31697aa8.mp4

Can't replicate the flickering thing in momentum, although it does get darker if I noclip outside world. As for the missing lines, seems to be caused by bug in CS:GO rendering fast path, is fixed by cl_tlucfastpath 0. Happens on DX9 as well.
