Unfortunately no. The backtrace looks like this now:

So all shader binds are giving GL_INVALID_OPERATION? Damn, this is hard to debug in these conditions, I think I will have to find an AMD computer to fix it... Thanks for all the help.

Yeah, that's basically why I have the GT710 too, to have something from Nvidia to test things with. Have you tried using the Nouveau driver to see if you can debug the issue with that? It doesn't seem to support the required OpenGL version on my card though, so I'm not sure if it's helpful (using MESA_GL_VERSION_OVERRIDE to fake 4.4 support makes the game actually start and run into the same error, but then again that could be because something that's actually needed isn't supported by the driver).

Anyway, sorry for not being able to help any further. I have no idea about anything when it comes to shaders.

I just added in the latest commit more debugging options, can you pull, make clean, make gdb, and try again?

Well, now it keeps running after start with a window full of what I assume is garbage from the graphics memory. Here's an excerpt of the output before I killed it myself: https://pastebin.com/raw/QXDxsZh4

That's new information though,

GL_INVALID_OPERATION in glUseProgram(program 5 not linked)

Apparently, it didn't get linked somehow... I've added a debug print to check if the program gets linked correctly. Again, tell me to stop giving you things to do if I'm pushing.

Wow, your graphics card is giving me nothing...

I changed a lot in the shaders, could you check if the repo version fixes your problem?
