--- Comment #1 from Arjen Hiemstra <ahiems...@heimr.nl> ---
The implementation of Line charts was changed to use vertex attributes for
passing data, as that allows for several improvements to rendering performance.
According to the OpenGL documentation, the minimum amount of vertex attribute
components an implementation should support is 16*4, or 64. This is even true
for OpenGL 2.1, see
https://www.khronos.org/registry/OpenGL-Refpages/gl2.1/xhtml/glGet.xml . That
means that your OpenGL driver is not conformant, as it claims to only support
10*4 vertex attribute components. There isn't much we can do about this on our
end, I don't really want to hurt other drivers because of one non-conformant
driver and there's no easy way to fall back here.
You should really report this to the upstream driver.
