No textures

[ghost]

Hello, I've followed your instruction to run sucle on Arch Linux using SBCL.

The game runs fine, except it start with a black screen, and then I have no textures.

Hello marespiaut,
This might be an OpenGL version issue, what version are you using?

[Drainful]

I'm having the exact same issue, OpenGL version 3.0 Mesa 18.1.7

[gregcman]

Display lists must not be working. A fix would require porting display lists to vbo

Edit: @Drainful if you have OpenGL 3.0 Mesa I don't know what could be wrong, because 3.0 supports legacy OpenGL

The issue disappears when I run sucle on my nvidia gpu (laptop with nvidia optimus), so that sounds like a good guess.

Edit: The gpu on which the issue occurs is an integrated intel.

@Drainful It is not obvious why the OpenGL version 3.0 Mesa 18.1.7 would produce the pictured results, but nvidia optimus would not. It could be a number of things:

• Legacy OpenGL? [probably not, because 3.0 should be supported.]
• sucle not following the OpenGL spec close enough, with bugs that don't work on some setups
• implementation-defined limits exceeded?
• mesa driver bugs?

for the integrated intel gpu, it would be helpful if you ran and shared the diagnostics in this link

[Drainful]

Output is in the link. I'm running Nixos so dpkg isn't a thing and tbh I don't know the equivalent.

Sucle now uses VBOs or display-lists depending on the OpenGL version, so these issues should disappear.

The issue has been solved for me as of the latest commit
