Textures not showing

[Eusebius]

Hi. In my current installation, most SSTU parts appear black in the VAB or in flight. I haven't tested everything of course, but PC-DRC renders fine while the MFT-A tank (any texture) and most others remain black. On some parts, like the SCE-WL left wing, most of the part is black while a subpart (the landing gear and its trap) renders properly.

I'm using version 0.12.50.162 on KSP 1.8.1.2694, on Linux 64bits (so, OpenGL I guess).
I have removed all mods other than what's in the SSTU zip file.

In my graphical settings, rendering is "fantastic", texture quality at full resolution.

Any help or directions would be greatly appreciated.

A lot of "texture not found" in my logfile.
