<br>
For reference:<br>
<br>
i managed to fix this by switching to QVTKOpenGLWidget. Unfortunately this<br>
requires PCL from master (for reference: this<br>
<a href="http://www.pcl-users.org/QVTKOpenGLWidget-Qt-PCLVisualizer-td4045158.html" rel="noreferrer" target="_blank">http://www.pcl-users.org/QVTKOpenGLWidget-Qt-PCLVisualizer-td4045158.html</a> is<br>
not yet in a released version).<br>
<br>
Now i have some other issues: i need to run it with<br>
MESA_GL_VERSION_OVERRIDE=3.2 otherwise i get this:<br>
<br>
vtkShaderProgram (0x563e8e366510): 0:1(10): error: GLSL 1.50 is not<br>
supported<br>
<br>
thanks,<br>
