Wrong number of samples

[Celant]

Clean install on Arch, build and install with yay seems to work fine, but when running glmviz I get the following:

╭─joshha@joshharris-m15:~
╰─>  glmviz
terminate called after throwing an instance of 'std::invalid_argument'
  what():  Wrong number of Samples
zsh: abort (core dumped)  glmviz```

That error has something to do with Multisampling, so it's probably graphics driver related. Could you send me your glxinfo output?

If you are feeling a bit adventurous, you can also try out the improved project at: glmvng

Hey thanks for getting back so quick. Output of glxinfo can be found here. I'm happy to try glmvng if you can help convert my config from glmviz? I'm just able to understand the glmviz config, let alone trying to convert it to something else :)

I added some more debugging stuff around the multi-sampling code, that should help me finding the cause of this bug.
In the meantime you have to disable multi-sampling in your config using the following settings:
Window = { AA = 0 }

As for glmvng, the configuration might be a bit harder, but it allows you to write your own shaders.
I'm still working on it so things might still change.

Looks like your debug stuff fails to compile:

Disabling multi-sampling in the config does work for the meantime 👍

Oh I forgot to update the CMake file.
