Custom (HD) texture packs in Dolphin Emulator

[Luxdragon]

Greetings,

I have an issue with Linux Mint's Dolphin emulator

So, I downloaded the emulator from the Software Manager and I want to play Metroid Prime 2: Echoes. I have decided to use the same HD graphics pack, which I used on Windows. I renamed the graphics pack and put in the /my-username/.local/share/dolphin-emu/Load/textures folder, just like in Windows and I set the Dolphin Graphics settings option "Load custom textures" on. On Windows the HD texture pack works, but it is not loaded on Linux Mint. Why? Everything else works just like on Windows.

I also tested the flatpack version, but the texture pack also didn't get recognised there.

Kind regards
