Hello Michael,

Thanks for your help, but sorry for my ignorance, I do not know anything about SDL programming, that code was an example suggested by the AI.
Also have tested sdlpop game from pkgsrc and fails the same with garbled background. It seems that all SDL based programs fail here.

Do you have please a little piece of SDL C code that you know works there to test here and see what happens?


Thanks in advance.
Regards.
Ramiro.
