[pygame] Surfaces must not be locked during blit

["Sibtey Mehdi" <sibteym@xxxxxxxxxxxxxx>]

Hi

I am drawing some graphics page (Text, rect, lines, polygon) on pygame surface, but when I quickly pressing page up and page down my application give the Pygame error “Surfaces must not be locked during blit”.

I have also unlocked the surface by suface.unlock before blitting but it doesn’t solve the problem.

So please help me out of this problem

 

Thanks,

Sibtey
