Custom Textures and Rendering Resolution bug

[Ezehokadrim]

Alright so the texture filtering cannot be fixed because it's a game's issue, got it. And about the texture upscaling I found out why I thought it didn't work at the same time. When you change most settings, the effects are seen instantly. In texture upscaling's case, the changes are only seen when the textures are reloaded (for example, I loaded a savestate again) regardless of custom textures being on or not. I didn't notice that behavior at first so sorry for the useless question. And I guess in the end there was no bug. Thanks for all the info then!
