Symptoms

When viewing a memory fragment (either from Trace Memories menu or during gameplay ), there's black boxes surrounding the "sprites".

Reproduction

• From "Trace Memories Menu" -> click on any leaf/memory fragment (for example 1).
  • Needs savefile: savedata.zip
  • Place savedata.sav under SteamLibrary/steamapps/common/htoL#NiQ The Firefly Diary/data/save/
• Found during normal gameplay.

Start by reproducing the issue from the Trace Memories Menu using the provided savedata.sav, then review steam-368640.log alongside the screenshots and listed Proton versions. Done means the memory fragments and normal gameplay render sprites without black boxes on the reported system.
