Linux build 120208

Another build ready for brave Linux users.

When testing on Archlinux with the proprietary Nvidia driver I get the same exact error log as flesk in the previous pinned post. It looks like there might be some sort of incompatibility with the Nvidia OpenGL libraries as it works with software rendering.

I discovered an ugly hack for Nvidia:

#!/bin/bash

Xephyr -br -ac -noreset -screen 1600x900 :2 &
sleep 1
DISPLAY=:2 openbox-session &
sleep 1
DISPLAY=:2 ./Delores

The game will launch with OpenGL software rendering in a nested Xephyr X-server. It needs to have a simple backing window manager like openbox to work.

Edit: Still fails to launch without Xephyr as of build 120208

Linux Mint 20 + Nvidia 440.100, same as previous builds:

@RonGilbert
Could you include in the logs the vertex shader that is failing?
My uneducated guess is that the shader might not be fully compliant with the spec, but most of the drivers are fine with it, but Nvidia has more stricter rules (???)

Starts and no issues clicking around for a few minutes. Arch with AMDGPU. :+1:

The log output is slightly different this time, as it no longer contains ZLOpenGLRenderer: Failed to create an EGL context. (error 0x3006). Otherwise, it’s exactly the same (except the different build number and timestamps).

Ubuntu 20.04 with nvidia-driver-440. The game does not start.
