Background Transition Blurry (Linear Filtering)

[NatePlays95]

The problem

Describe the bug Background image transitions become blurry during any of the default background transitions, despite the chosen default texture filtering in Project Settings

To Reproduce

• Set project setting rendering/textures/canvas_textures/default_texture_filter to Nearest.
• Get a pixelated / low resolution image to use, like a texture from Spriters Resource.
• Make a new Timeline.
• Set a Simple Fade or Push transition to a pixelated / low-res background image (Make it slow for easy notice).
• Preview Timeline.

Expected behavior The filtering mode for the background transition shaders should respect the filtering mode I set as default in the editor in rendering/textures/canvas_textures/default_texture_filter, and I possibly be able to edit the filtering mode as a setting of the BackgroundLayer in the style editor.

System (please complete the following information):

• OS: Windows
• Godot Version: 4.2
• Dialogic Version: 2 alpha 14

Solutions

Workaround

My game is made entirely with pixel art so I can afford modifying the default shaders directly.

Possible fixes If possible, these sampler filter types should be set to the system default when the shader is instantiated.

I agree that this would be better behaviour, though I'm not sure if this is possible without switching out the whole shader. This seems to be the relevant godot issue: https://github.com/godotengine/godot/issues/57679
