Some old apps write surface data past the end of locked space. That
used to work on early ddraw hardware as locked surface provided
direct access to video memory mapped to CPU address space and such
access could often go without issues. Currently ddraw on Windows
allocates bigger buffers for video memory surfaces when 8 or 16 bit
display mode is requested.
