我正在为Android和iOS开发游戏。这是一个非常简单的项目，因此所有材质都使用LWRP Lit着色器。我试图在iPhone 6s和iPhone XR上构建游戏。在我的每台Android设备和iPhone XR上，它都能正常运行。但是在iPhone 6s上，在加载游戏场景之后，我就冻结了图形伪像。
在Xcode中存在这些错误：
在一开始：
ERROR: Shader Shader is not supported on this GPU (none of subshaders/fallbacks are suitable)
WARNING: Shader Unsupported: 'Hidden/Lightweight Render Pipeline/ScreenSpaceShadows' - Setting to default shader.
ERROR: Shader Shader is not supported on this GPU (none of subshaders/fallbacks are suitable)
WARNING: Shader Unsupported: 'Hidden/PostProcessing/Debug/Waveform' - Setting to default shader.
ERROR: Shader Shader is not supported on this GPU (none of subshaders/fallbacks are suitable)

ERROR: Shader Shader is not supported on this GPU (none of subshaders/fallbacks are suitable)

ERROR: Shader Shader is not supported on this GPU (none of subshaders/fallbacks are suitable)

ERROR: Shader Shader is not supported on this GPU (none of subshaders/fallbacks are suitable)
WARNING: Shader Unsupported: 'Hidden/PostProcessing/Debug/Histogram' - Setting to default shader.
最后（循环）
Execution of the command buffer was aborted due to an error during execution. Ignored (for causing prior/excessive GPU errors) (IOAF code 4)
现在我正在使用Unity 2019.1.0a10，但以前我试图使用2018.3.0.11b和2018.2.17f1进行构建。我也尝试了几种版本的LWRP，但结果仍然相同； c
