--- Comment #4 from NSLW <lukasz.wojnilow...@gmail.com> ---
I think it's not a downstream issue anymore. Line chart graphs worked on
kquickcharts v5.85.0 and stopped on v5.86.0. My regression test gave following
result. Please fix it.

Implement batching for Line chart material
This allows line chart segments and the respective material to be
batched, by sending per-segment data as vertex attributes rather than
uniforms.
Unfortunately, OpenGL 2.1/GLSL 1.10 doesn't support array vertex
attributes, so instead this emulates an array by simply defining a bunch
of vertex attributes and manually converting it to an output array.
