Castlevania: Legacy of Darkness - Character selector doesn't display the highlighted character properly in Low-res

Summary

On the character select screen, the cursor that appears to highlight your chosen character does not display the character behind it when the expected behavior is that it does. All portraits that are not behind the cursor at the current moment show up just fine. The core is Mupen64Plus with GLideN64 as the plugin. When I try testing on standalone Mupen64Plus (via up-to-date Simple64) the portraits show up just fine behind the cursor as they are supposed to, which leads me to suspect a Bizhawk-specific issue. It's worth noting that this only appears to occur on both NTSC versions of the game (hashes are 25258460f98f567497b24844abe3a05b for US and 47ea239717c4d225c9d0e9fd37b9fcb3 for JPN) and on Low-res mode. On the PAL version (78d5f8a98a5ed21d0817856bcd2ad750) and NTSC Hi-res mode, the portraits display behind the cursor fine. No tools or scripts are open.

Repro

1. Open a Castlevania: Legacy of Darkness NTSC ROM normally.
2. If no save data is created, make sure that Memory Card is chosen for Controller 1 under N64 > Controller Settings, reboot core, and pick "Create CASTLEVANIA2 Note" on the scroll menu that appears.
3. On the Expansion Pak screen, pick LOW for Low-res mode or HIGH for Hi-res mode.
4. Proceed through the new file creation process until you reach the character select screen. If you picked Low-res, the highlighted character portrait will be invisible. If on Hi-res, it will be visible.

Use the attached SAVERAM file to unlock all characters for easier testing:

Host env.

• BizHawk 2.9.1; Win11 Intel/NVIDIA
• BizHawk 2.8; Win10 and 11 Intel/NVIDIA
• BizHawk 2.7 and 2.6; Win10 Intel/NVIDIA

Reproduce the issue using the supplied SAVERAM with the NTSC ROM in BizHawk, comparing LOW and HIGH modes and the PAL version. Start by examining the Mupen64Plus core and GLideN64 plugin behavior, using standalone Simple64 as a comparison; done means the highlighted portrait displays in NTSC Low-res without regressing the working modes.
