[Android][GI] Blocky artifacts in lightmap
In a very simple scene the baked lighting on a static cube is rendered smoothly on Desktop but has green splotches on Android. My best guess is that these blocky artifacts are due to GI from the ground region of the default skybox, but the result is not what I would expect.
Test configuration:
- Unity 2020.2.1f1 (2020.2/release 270dd8c3da1c)
- URP 10.2.2
- Build settings = Android
- XR or non-XR app on Quest; or Play mode on Mac
- Bug also occurs on Unity 2021.2 (trunk da76c15a8bcc) + URP 11.0.0
The repro scene:
- Default skybox.
- Pure white realtime directional light, intensity = 0.3.
- A static cube, and a static plane.
- No light probes, no reflection probes.
- Project settings > Quality > Ultra

Resolution Note (2020.2.X):
By design: Android uses lossy lower quality texture compression. To increase the lightmaps quality, select the lightmap texture and override format into desired quality, note that some formats might not be supported by all Android devices.
