Set both Clamping Modes to their highest values (Extra & Full + Preserve Sign). If you are in the battle it does not change anything. You have to restart the game.

/to rama Sorry I don't have any at the moment. Here are the known battle that the bug occurs:

• The underwater boss found outside Baaj Temple early game. Character affected: Tidus
• Mi'ihen Operation Sinspawn battle. Character affected: Seymour
• The elemental fiend in Macalania wood, before viewing Jecht's sphere. Character affected: the character that stands in the middle
• Yunalesca battle. Character affected: both the character that stands in the middle and Yunalesca
  

It takes about 30 mins to reach the underwater boss outside Baaj Temple boss. Somebody please do it if you time.

No it worked i just had to restart the emulator
