I re-checked with svn52211 and the glitch is still there.
If you can't reproduce this, I am willing to help. I am a (C#) programmer, so I guess that with a little guidance I could trace the source of this.

It seems this bug could be the same as the lsl5 dream sequence bug, where kDrawPic is called while a textbox is shown. Which results in no transition taking place, so the old picture will stay on screen.

LSL5 got fixed later, SQ5 1.04 is also fixed (user has 1.03). I also don't have 1.03, so can't test here, although i got the problematic lsl5 version.

@ omer_mor: please enter "logkernel DrawPic on", "logkernel NewWindow on" and "logkernel DisposeWindow on" in debug console (Ctrl-D to access it) during the scene right before that issue and then post the results from the text console in here.

The glitch in image #2 just looks less better - but not fixed. I attached a new image of that screen.

Yes it does (using 1.3.0svn53938).

OK, from the sound of it, it looks like you have corrupted game files. Please, try recopying the game files from the original media. If the problem still persists, please provide the MD5 files of the full file contents (rather than the first 5000 bytes) - use something like MD5 summer for Windows (

comment:21 by OmerMor, 9 years ago

I don't believe my files are corrupt: DosBox plays this scene flawlessly.
However - here are the md5s:

I tried it again today with the latest 1.3.0git daily version and the glitch still occurs.
Like I said in one of the earliest comments: I am a programmer myself (in C#, but it doesn't matter). I could help you debug it on my machine if you'll just give me some pointers.

comment:32 by bluegr, 9 years ago

Thing is, we got no idea why this occurs in your system, and none of us could reproduce this :( SCI is very complex, so it could be anything. So, even if you are a programmer, there's little we can do about this.

I did try this with MSVC, both with Debug and Release builds, under Windows 7 64-bit, both 1.03 and 1.04 versions. Others tried it with gcc under *nix. Nobody could replicate it. Thus, if this can't be reproduced, there's not much we can do to help, I'm afraid :(

comment:34 by wjp, 9 years ago

Which of the three screenshots you posted still occur for you with current snapshots?

Can you say _exactly_ what you do after the scrubbing finishes? Do you click through any of the dialogs in the cutscene? Do you wait for it to finish uninterrupted?

comment:35 by OmerMor, 8 years ago

screenshots #1 & #3 still occur with current snapshots.
After the scrubbing finishes, I click through all the dialogs in the cutscene until I get to the glitch.

(BTW - I tried to save myself the trouble of waiting by saving the gaming right before the cutscene ends using the console debugger save_game command. However when I try to restore that save, I get an exception. I guess the engine does handle well save games from within a cutscene, but I accept this as it was not supported in the original engine either)

comment:36 by wjp, 8 years ago

Does it also happen if you let the cutscene happen uninterrupted? (Just wondering if it depends on the timing of the clicks, for example.)

Judging by the screenshots, it looks like outdated underbits are being restored to screen after a scene change. If you could figure out where they come from (given your offer on the forums), that could be helpful. A starting point for that might be determining the exact rectangle that is broken, and putting a breakpoint on GfxScreen::bitsRestore (in graphics/screen.cpp) when it restores that rectangle. The last time that breakpoint is triggered is then likely the wrong call.

comment:37 by OmerMor, 8 years ago

New findings:
1. When debugging this it's not always happening (the 2 graphical glitches) - behaves like some race condition.
2. The script is also behaving wrong: In DosBox, after Quirk is slipping, Beatrice is laughing at his toupee. Quirk says "arrggh", and then says something like "you did this on purpose Wilco". However in ScummVM, the first 2 text balloons are shows very briefly, and immediately replaced with "you did this on purpose Wilco", accompanied with the graphical glitch".

Maybe the script bug will be easier to debug.

comment:38 by digitall, 8 years ago

My copy of SQ5 is v1.04 and does not exhibit this issue.
However, loading savegames (from the launcher) in the Scrubbing Scene can result in not being able to complete the scrubbing i.e. the script fails to detect success..

I did check and no valgrind issues including un-inited reads are associated with this issue.

I suspect that the v1.03->v1.04 have fixed/masked the gfx issue, but it appears that the Scrubbing Scene scripts are probably fairly brittle and should be analysed to see if a patch can be made to correct them.

Just checked this with 1.6.0git240-g52a1a6e, and the glitch appears to be solved!
