Text rendering problem with hello-world example
Hi maintainers, thank you very much for this project!  I'm having one issue on my machines with the `hello-world` example, specifically with the text rendering.  This is what I'm seeing on my arch linux machine and also on another 2019 MacBook Pro machine.

If I try rendering some text other than `"Hello, world!"`.  This is what I see:

- 5 a's (i.e. `"aaaaa"`):

I'm still learning more about computer graphics and the GPU so I don't quite know how to troubleshoot this issue.  It'll be really appreciated if you can help me to troubleshoot this.  
I have the lastest master of `lispgames/cl-sdl2` and `lispgames/sdl2kit` in my `local-projects` directory.  Here's my opengl version information:
