      Found originally in QtGraphs: qml_injection test with the following error: 

      Combined image sampler duplicates an existing binding number 3
QRhiShaderResourceBindings(QVarLengthArray(QRhiShaderResourceBinding(binding=0 stage=QFlags(0x1|0x10) type=0 UniformBuffer(buffer=0x2000cd485f0 offset=0 maybeSize=516)), QRhiShaderResourceBinding(binding=1 stage=QFlags(0x1|0x10) type=0 UniformBuffer(buffer=0x2000cd485f0 offset=768 maybeSize=304)), QRhiShaderResourceBinding(binding=2 stage=QFlags(0x1|0x10) type=0 UniformBuffer(buffer=0x2000cd485f0 offset=2304 maybeSize=816)), QRhiShaderResourceBinding(binding=3 stage=QFlags(0x10) type=1 SampledTextures(count=1 texture=0x2000cf89bd0 sampler=0x2000ca909f0)), QRhiShaderResourceBinding(binding=3 stage=QFlags(0x10) type=1 SampledTextures(count=1 texture=0x2000cf89bd0 sampler=0x2000ca909f0)), QRhiShaderResourceBinding(binding=4 stage=QFlags(0x1|0x10) type=1 SampledTextures(count=1 texture=0x2000cf8a8c0 sampler=0x2000ca906d0))))

      The texture in binding 3 referred to the shadow map texture

      The attached example sometimes yields a slightly different error but also crashes
