A similar bug occurs in FOA (German version, Non-Talkie at
Actors leave "traces" when walking across the screen.
This appears to happen only in a small area on the left side.

(Walk around in front of the big box and you'll leave traces)

This bug is reproducable for me (Linux/SDL port)

comment:3 by SF/schneiper, 16 years ago

I think the problem is the text should removed from the
screen befor scrolling begin and not after the picture
scroll the first part.

comment:4 by fingolfin, 16 years ago

ursg's problem turned out to be caused by a bad CVS build, and is
gone. Your first bug looks suspiciously similar...

Do you compile CVS yourself or do you use the dialy built binaries we

Since I don't have the german MI2, I can't try that save game. But no
the text should not be removed before the scrolling begins, rather it
should be scrolled correctly :-)

i have testit again.

I cant adjust Problem1 with this smal test.

Problem2 was NOT in v0.3.0b (last non CVS) but in many CVS
builds up to 0.3.7cvs Built on Apr 27 2003. I can adjust too
by Kaptn Kate at Booty Island.

comment:6 by fingolfin, 16 years ago

What do you mean with "adjust" here? This sounds like an improper
translation from German, although being German myself I still don't
understand it :-) (BTW is a really great online

Did you want to say: You still get Problem 1. Or did you mean You do
not get it anymore?

comment:7 by SF/schneiper, 16 years ago


What i mean is...
In a smal test, i do not get it again Problem1.

comment:8 by fingolfin, 16 years ago

First does, this still happen with the very latest CVS?

Sadly I can't open that german save game. Hm, maybe you can tell me the
room number. Press "#" key to get into the debugger, then enter the "room"
command - this will tell you the room number. One can then "teleport" to
that room by using "room NUMBER".

If you tell me the room number on Dinky Island, maybe I can teleport there
and reproduce the bug this way.

the roomnumber is 85 (Dinky Island) but i cant "teleport"
in this room.
The same bug exist on Booty Island, in front of Stans Shop,
when Kaptn Kate talking and the screen scrolling.

You still didn't tell us if this is with latest CVS, though.

ScummVM 0.4.2cvs
Built on Jun 8 2003 10:48:38

comment:15 by eriktorbjorn, 16 years ago

I've seen the scrolling text problem appear in other cases
as well. (I have a savegame at home that demonstrates it in
FOA, for instance.)

I noticed our setCameraAt() function will call stopTalk() in
some cases (shouldn't that be restoreCharsetBg() instead, or
do we really want the actor to stop talking as well?) but I
don't think that's enough to catch all cases, e.g. when the
camera pans or follows an actor.

Perhaps that should be in cameraMoved() instead, but I don't

comment:16 by fingolfin, 16 years ago

I made a change to cameraMoved which updates gdi._mask
when the camera moves, fixing a similar problem in The Dig. I
wonder if that helps here, too?

Erik, the stopTalk() is there in the original,too, at least for V1-V3
games. I don't have access to V5+ disassmbly right now, so i
can't tell if they do it, too. But note, ScummVM was based on a
V5 game, so it's likely to be correct there, too. Since V7/V8 uses
a separate version of setCameraAt(), that only leaves V6 games -
maybe there stopTalk() really shouldn't be called. Dunno.
