World name: Hyperion
Character name: Myranda Al'Cyoene
Class/Level: 60ROG/NIN
Party or solo: solo
In-game time: any
Area and coordinates: The Roost (Gridania Inn) originally discovered, seems to occur at any location

Steps:
1. Equip Sophic Points directly from inventory/armoury chest (such that class changes to rogue, but the Ninja soulstone is NOT equipped)
2. Equip the Ninja soulstone

Result:
Upon equipping the soulstone, the weapon display expands from its normal on-the-hip sizing to the sizing that normally occurs only when the weapons are drawn for battle. The bug disappears if the weapons are unsheathed and then resheathed.
