Luminar Light ed028a4e8a jak1: Fix hint subtitles sometimes missing (#4440)
Some months ago I noticed that I wasn't seeing hint subtitles in TPL
anymore. Specifically, I was seeing the speaker names, but not the
subtitles themselves. I looked into it briefly back then and failed to
find anything, so I assumed it was something wrong with my setup
somehow.

I have returned to the issue, and managed to fix it. Now I consistently
see all subtitles, as I should. I always had the subtitles in the other
games working fine, and after my fix I still see them.

Before:

/>

After:
<img width="1920" height="1080" alt="2026-10-10T16-58-55"
src="https://github.com/user-attachments/assets/4e58b34b-a253-458b-8be0-877c73767c3b"
/>

The fix was to provide default values in the subtitle metadata structs.
I remember that c++ fields/structs can end up having garbage data if you
don't provide values yourself, and this is probably also influenced by
the build config and maybe the PC itself. Anyway, with these changes, it
should always be good now regardless of who or what builds the project
(I usually use the Release msvc build config because Release clang has a
history of failing me).

Maybe it is worth mentioning that I always play with the setting that
forces speaker name to appear at all times. Not sure if relevant.

I have also discovered that the reload-subtitles feature of Jak 1 was
not working anymore, so I have made some adjustments and now it is
working fine.

While my solution fixed my issue, it is possible that it is not the
right way. The c++ language is not a language I am very experienced
with, so if my solution is unprofessional, please let me know and tell
me how I should approach it instead. But I am certain that the issue is
with field initialization somehow, and this is one way to fix that.

EDIT: Worth mentioning that I properly see all subtitles in current
latest OpenGOAL (launcher v2.11.2, tooling v0.3.8), which further
reinforces the idea that it is some fields that get unpredictable
values, influenced by the build config or build device. My issue is only
when I build the project myself. And it may impact other people, or it
may become an issue for official OpenGOAL too in the future.
