URP SMAA produces wrong results on mobile when using default sampler precision
SMAA on mobile has degraded quality compared to desktop.
Setting "Use full sampler precision by default, lower precision explicitly declared" in the project settings makes the issue disappear
Reproduction steps:
1. Open the URP template
2. Set the build target to iPhone
3. Make sure that "Project Settings" -> Player -> iOS -> "Other Settings" -> "Shader Settings" -> "Shader precision model" is set to "Use platform defaults for sampler precision" ( if not available do nothing)
4. Build for iOS
5. Capture screenshot (preferably via Xcode Metal capture, as that won't resample the image)
Expected result:
SMAA output is mostly equivalent to Play Mode on Mac. The capture at step 5 is identical to a build where step 3 were set to "Use full precision by default, lower precision explicitly declared"
Actual result:
SMAA edges are jagged, output is different (regressed) with sampler precision set to default from desktop and from forced full precision
