Any idea why this happen with the textures?

Hello, I'm currently playing Star Wars Bounty Hunter with a modified ISO with the Widescreen patch from PCSX2 on PS2Net_Emu (PS2 emulator for PS3). 
I've noticed that the textures of some NPCs simplifying when I activate the game's first-person view mode but they return to normal when I deactivate them or reach a certain level of proximity 

I tested the PS2 Classic version of the game and this does not happen. I tried adding some configuration files (CONFIG) but nothing seemed to help.

Any idea why this is happening? If it's the Widescreen Patch causing it, is there any way to fix it?

I appreciate any help.

For the record: the modified ISO is an extracted and mounted ISO of my original Playstation 2 copy bought in 2007 and the PS2 Classic version was purchased on PSN. No games were pirated here. Thanks.
