I'm writting an ordinary tetris implementation, to get along with Allegro. Yet I have to face a simple problem. I don't actually know how can I best implement anti-lasting. Since all I'm drowing are simple lines and rectangles I might just draw it on 2 (4) or even 4 (16) times bigger bitmap, but I hope there is a better way.

By the way I'm using Allegro5 on Linux.

You're completely right!

This happens to me quite often, though.

You probably saved me hours of looking this up, thanks!

PS. I think this topic should be removed to not confuse others.
