tell where this comes from, but it's either the OpenGL library or
your
graphics card.
As I mentioned, all the opengl demos with FPC works fine here.
I understand you, but these widgets make use of "special" features.
They use hardware acceleration by using GLSL.
Can you also
email me the output that you get from glutdemo.pp found in fpc
opengl/examples. This example will list quite some GL information to
console. We'll probably find a clue there.
----8<-------------8<-------------8<-------------8<-------------8<----
[examples]$ ./project1
GL info:
Vendor: Advanced Micro Devices, Inc.
Renderer: Mesa DRI R600 (RV710 954F) 20090101 TCL DRI2
Version: 1.5 Mesa 7.7.1
This seems to indicate that you use an older version of OpenGL (1.5).
AFAIK GLSL was included from OpenGL 2.0. So this suggests you should try
to update your libraries.
