Issue Description

An uiBackground configured with an atlas texture and wrapMode: "repeat" renders correctly on desktop but shows a weird/incorrect stretch on mobile when the image is set to fit 100% of the screen.

Reported by Alejandro Picazo with the following scene code:

uiBackground = {{
    texture: {src: resources.assetFolder.ui + 'new_catch_atlas.png', wrapMode: "repeat"},
    textureMode: 'stretch',
    uvs: [
        state.uvOffsetX,       0.8,
        state.uvOffsetX,       1.0,
        state.uvOffsetX + 1.5, 1.0,
        state.uvOffsetX + 1.5, 0.8,
    ]
}}

Expected Behavior

The atlas texture with wrapMode: "repeat" and custom UVs should render identically on mobile and desktop — no unwanted stretching of the image.

Screenshots / Media

Two screenshots were attached in the originating Slack thread showing desktop (correct) vs mobile (stretched) rendering — not included here, ask reporter to attach directly to this issue if needed.

Steps to Reproduce

1. Configure a uiBackground with an atlas texture, wrapMode: "repeat", textureMode: "stretch", and custom UVs (as above) sized to fit 100% of the screen.
2. Run the scene on desktop — image renders correctly.
3. Run the same scene on mobile — part of the image gets a weird stretch.
