ScummVM

Latest ScummVM snapshot
Swedish Freddi Fish 1

When Freddi and Luther read the message in a bottle, there's a tiny
graphics glitch at the moment where Luther says he's going to be rich. See
screenshot at http://www.update.uu.se/~d91tan/ScummVM/freddi.png

The glitch is the black pixels left in Freddi's eyes, and possibly at the
right side of her mouth as well. Since this happens at the very beginning
of the game, I'm not attaching a savegame.

This is probably the relevant part of script-45 (I had to use the
undocumented -9 option to descumm it):

[086E] (5D) if (localvar0) {
[0874] (C9) kernelSetFunctions.queueAuxBlock([VAR_EGO])
[087C] (C9) kernelSetFunctions.queueAuxBlock([localvar2])
[0884] (61) drawObject.setState(952,1)
[088B] (9D) actorOps.setCurActor(VAR_EGO)
[0890] (9D) actorOps.setAnimVar(0,0)
[0896] (9D) actorOps.setCurActor(VAR_EGO)
[089B] (9D) actorOps.setTalkPos(-220,50)
[08A2] (9D) actorOps.setTalkColor(216)
[08A6] (9D) actorOps.setTalkieSlot(1,"@T4618797,26778@I'm going to be
rich when I find that treasure!")
[08EE] (82) animateActor(VAR_EGO,9)
[08F4] (82) animateActor(localvar2,7)
[08FA] (82) animateActor(localvar3,10)
[0900] (5C) until (getAnimateVariable(VAR_EGO,0)) {
[0909] (6C) breakHere()
[090A] (**) }
[090D] (**) }

Which leads me to think that maybe there's an off-by-one error when
ScummEngine_v71he::preProcessAuxQueue() restores the background. If I add 1
to the right and bottom of the rectangle, the glitch goes away. Of course,
I'm not saying that this is necessarily the right way of fixing it.
