Re: [AD] OpenGL errors on Android

I don't have much to go on but there's this: you should destroy your shader before ACKNOWLEDGE_HALT but looks like you're doing it in on display found. I guess you're not actually using DISPLAY_LOST/FOUND on Android are you, just reusing Windows code? In any case everything should be released before acknowledging the halt.

And one more when I try to destroy/re-create a shader I'm using:

Does these two look like a bug in my code, or in Allegro? What more can I do to investigate?
