main menu without background textures

I found a driver and gpu independent regression, which apparently affects just
Sacred 2 Gold (installer from GOG). Tested GPUs were AMD RX 5500XT (NAVI14)
with AmdVLK as well as RADV, Nvidia Quadro M2000M with nvidia and Intel HD
Graphics 520 (Skylake) with ANV.

Regression symptoms include the missing background tree in the main menu, a
blackscreen in singleplayer and missing non-plane textures in multiplayer (no
movement control however).
> From the Protondb reports I figured, that this worked originally on at least

Intel and Nvidia, so I started looking for a regression since the reported wine
versions.
