 '''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 [https://forums.scummvm.org/viewtopic.php?t=16904 here],
 there seems to be a weird visual bug with ''ScummVM'' while capturing
 Adventure Game Interpreter engine games 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, the text boxes disappear in both the recording ''and'' the
 preview window, but still appear in the ''ScummVM'' window like nothing's
 wrong.

 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.
