Broken Shader Presets

The following shaders are known to be broken due to various issues.

This list is updated as of slang-shaders@33876b3

Broken due to parsing errors

librashader's preset parser is somewhat stricter than RetroArch in what it accepts. All shaders and textures in a preset must resolve to a fully canonical path to properly parse. The following shaders have broken paths.

  • No known broken presets.

librashader's parser is fuzzed with slang-shaders and will accept invalid keys like mipmap1 or filter_texture = linear to account for shader presets that use these invalid constructs. No known shader presets fail to parse due to syntax errors that haven't already been accounted for.

Broken due to preprocessing errors

The preprocessor resolves #include pragmas in each .slang shader and recursively flattens files into a single compute unit.

  • bezel/Mega_Bezel/shaders/hyllian/crt-super-xbr/crt-super-xbr.slangp: GLSL error: ERROR: common-functions-bezel.inc:63: 'HSM_GetInverseScaledCoord' : no matching overloaded function found
