Text Boxes Not Appearing in Game Capture Recordings of AGI Games — at Version 2

Reported by: JoLiKMC Owned by:
Priority: low Component: Engine: AGI
Version: Keywords: OBS, recording, text
Cc: Game: Space Quest 1

Description (last modified by JoLiKMC)

ScummVM version: ScummVM 2.8.1 (Mar 16 2024 13:01:03)
Operating System: Windows 10 Pro version 2H22, build 19045.4651

Game: Any title using Sierra On-Line's "Adventure Game Interpreter"
(First noticed on Space Quest, Chapter I: The Sarien Encounter.)
Version of game: All versions
(Confirmed on 1.0X 1986-09-24/DOS/English and 2.2 1987-05-07 5.25"/3.5"/DOS/English versions)
Relevant save game: Not applicable (happens anywhere)

Bug details: On occasion, the text boxes or other instances of text printing will fail to be captured in third-party video recording software. The text or text windows will, however, display just fine in ScummVM.

How to reproduce bug:
(Note: This may affect other software as well, but this is how I did it.)

  1. Open ScummVM, then open OBS Studio and make a new Game Capture window, linking it to ScummVM.
  2. Open any version of Space Quest I (AGI version) in ScummVM.
  3. Start recording and type anything to generate a text message window.

Further details:
As documented here, there seems to be a weird visual bug with ScummVM regarding recording AGI engine games and trying to record footage under certain setups, such as using OBS Studio in "Game Capture" mode. It's not consistent, or maybe it only happens on certain frames or cycles. In OBS, particularly, it shows up in both the recording and the preview window.

I've tested this issue with a couple of different DOS games: Space Quest, Chapter I (v1.0x AGI 2.089, v2.2 AGI 2.917) and King's Quest IV (v2.0 AGI 3.002.086). Both of them displayed the same issues with OBS Studio. I tried changing the video settings as well, but that did absolutely nothing. In all likelihood, this is probably more the fault of Open Source Broadcaster than anything, but I figured it was worth retreading since this has happened to at least two other people.

I've marked this as a "low priority" bug because switching to "Window Capture" in OBS Studio seems to have solved this issue for me.

Sorry. The video renderer makes no difference, seemingly.

Added considerably more details. (It affects all DOS AGI 2.0 to 3.0 titles, at the very least.)
