The OpenGL raster does work, I mean you can use all "gl..." procedures and it will work, but Allegro.pas 5 "software raster" (i.e. the "al_..." procedures) does fail if you try to draw pixels (al_draw_pixel) or text (al_draw_text, etc.) but it doesn't fail if you draw lines (al_draw_line).
It isn't a big problem because you can do all graphic drawing using OpenGL but then you can't create textures or modify them on the fly (you can still load them from disk, anyway). On Linux it works without problem.
Allegro.pas 4 does work both Windows and Linux without problem, but it doesn't allows OpenGL.
