My first suggestion would be to alter all the lines in Sub InitSurfaces in the Dev and Game clients from

Code:

.ddsCaps.lCaps = DDSCAPS_OFFSCREENPLAIN Or DDSCAPS_VIDEOMEMORY

to

Code:

.ddsCaps.lCaps = DDSCAPS_OFFSCREENPLAIN Or DDSCAPS_SYSTEMMEMORY

If that doesn't do it, then maybe DX7 needs re-installing.

Can't be much more help than that I'm afraid.

It happens because the backbuffer isn't cleared before the next frame gets blitted to it.
The quick fix is popping this little bit of code into Sub GameLoop in both the dev and game clients.

Code:

With rec
    .Top = 0
    .Bottom = (MAX_MAPY + 1) * PIC_Y
    .Left = 0
    .Right = (MAX_MAPX + 1) * PIC_X
End With
DD_BackBuffer.BltColorFill rec, RGB(0, 0, 0)

Put it just after the check to see if the surfaces need restoring at the top of the sub.

Code:

' Check if we need to restore surfaces
If NeedToRestoreSurfaces Then
    DD.RestoreAllSurfaces
    Call InitSurfaces
End If

That should sort that out.

N.B. I noticed some more of my code in modDirectX is stuffed up too.
Where the surfaces are intialised.
