Graphical Glitches Playing FMVs with OpenBIOS and Dynarec CPU

[njfox]

Describe the bug

When used with OpenBIOS on my Fedora 41 machine, PCSX-Redux suffers severe graphical glitches when playing e.g. the opening cutscene in Final Fantasy VII. Green squares flash across the screen before the video locks up entirely, although audio continues playing normally. This behavior only occurs when Dynarec CPU is being used.

I tested with the official PSX BIOS and the issue does not occur.

Expected behavior

The FMV should play normally.

Steps to reproduce the bug

1. Run pcsx-redux (either the appimage or compiled locally) with Dynarec CPU configured and with OpenBIOS.
2. Launch Final Fantasy VII and click new game
3. Observe graphical glitches in Intro FMV
