#11 0xb4a6a8f7 in QMessageLogger::fatal (this=0xbfaa34fc, msg=0xaecdfa98 "QSGSimpleMaterialShader does not implement 'uniform lowp float %s' in its fragment shader") at global/qlogging.cpp:669
#12 0xaecc9a76 in QSGSimpleMaterialShader<FadingMaterialState>::initialize (this=0xb463138) at /opt/project-neon5/include/QtQuick/qsgsimplematerial.h:66
#13 0xaecc9059 in FadingMaterialShader::initialize (this=0xb463138) at /build/buildd/project-neon5-plasma-framework-0.0+git20140613.0308+neon4~111ef0b~14.04/src/declarativeimports/core/fadingnode.cpp:104
I'm confused. The relevant code in qsgsimplematerial.h:66 is
const char *opacity = uniformOpacityName();
if (opacity) {
m_id_opacity = program()->uniformLocation(uniformOpacityName());
if (m_id_opacity < 0) {
qFatal("QSGSimpleMaterialShader does not implement 'uniform lowp float %s' in its fragment shader",
uniformOpacityName());
}
}
I quite clearly do implement "uniform lowp float qt_Opacity;" in my fragment shader though, and I've not seen this crash anywhere else.
What graphic card do you have? Does this happen every time?

What I find interesting is that you use XRender compositing? Did you change to that? Could you please post the output of "glxinfo" (package mesa-utils) Created attachment 87238 [details]
glxinfo
I didn't change the compositing type (the desktop effects kcm module only shows a black box).
> OpenGL version string: 1.3 Mesa 10.1.3
I'm sorry to say: your hardware is not sufficient to run plasmashell. QtQuick requires OpenGL (ES) 2, but your hardware can only do OpenGL 1.3. Especially the extension GL_ARB_shading_language_100 is missing which is required to compile shaders.
You can try running the software with LIBGL_ALWAYS_SOFTWARE=1 to enforce the llvmpipe driver which runs on CPU. Be warned that this driver requires a multi-core system with SSE4 extension.
@devs: who should we try to catch these problems? Crashing is probably wrong, but we have hardly a chance to test the condition.
Created attachment 87246 [details]
Example source code to reproduce
To reproduce the crash one can do the following:
LIBGL_ALWAYS_INDIRECT=1 qmlscene icons.qml
this will open a window and print thousands of warnings that the Shader could not compile. If one clicks in the window the crash will be triggered as the fading starts.
LIBGL_ALWAYS_INDIRECT disables direct rendering and effectively sets OpenGL back to 1.3, so no shaders. With NVIDIA it's possible that it would not crash, as NVIDIA extended the glx protocol and AFAIK they allow shaders over indirect connection.

[declarativeimports/core] Do not crash if FadingMaterialShader failed to complie Without GLSL our shader doesn't compile and Qt aborts when accessing the uniforms.
