<pre>Hello,
I have an Intel HD620 graphic Card (Kaby Lake) and I wanted to use an OpenGL
audio plugin. I run Mageia 6 with Mesa 17.1.5 on a 64-bit System.
Here is my Output of glxinfo | grep OpenGL:
"OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 620 (Kaby Lake GT2)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.1.5
OpenGL core profile shading language version string: 4.50
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 17.1.5
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.2 Mesa 17.1.5
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20
OpenGL ES profile extensions:"
When I try to load the OpenGL audio plugin obviously the wrong shader
preprocessor string seems to be passed. The following error message is
outputed:
"** INFO: AF210 - System GL Version is: 3.0 Mesa 17.1.5
** INFO: AF210 - System GLSL Version is: 1.30 : #version 100
AF210::GFX_renderer::GFX-VXSHDR-03 failed to compile
0:1(10): error: GLSL 1.50 is not supported. Supported versions are: 1.10, 1.20,
1.30, 1.00 ES, 3.00 ES, 3.10 ES, and 3.20 ES
[...]"
But the developer of the Audio plugin expected accordingly
<a href="https://en.wikipedia.org/wiki/OpenGL_Shading_Language#Versions">https://en.wikipedia.org/wiki/OpenGL_Shading_Language#Versions</a> the following
string at the beginning:
"** INFO: AF210 - System GLSL Version is: 1.30 : #version 130"
Because the System seems not to have Version 1.30 the Audio plugin falls back
to GLSL Version 1.50 which the system doesn't support.
I don't know whether this is a Mesa Bug. To be honest I have not a hunch about
OpenGL. The audio plugin is OverToneDSP AF-210. A demo can be downloaded from
<a href="https://www.overtonedsp.co.uk/download/download_af210/index.html">https://www.overtonedsp.co.uk/download/download_af210/index.html</a>
You can find my bug report at OvertoneDSP at

It would be great if you could help me.
Thanks in advance,
Max</pre>
