I never experienced problems like that. Yes, make sure you handle the backbuffer correctly. If you completely omit to set it, the output may be pretty randomly.
Also make sure to set the window or fullscreen mode since Blitz will use windowed in debug mode and fullscreen mode in release when you omit that setting, if I remember right. so
Graphics3D 640,480,32,2
setbuffer backbuffer()
...
while not game_end
; do things
flip
wend
Should look the same in both modes.
