glBufferData(GL_ARRAY_BUFFER, m_vertexPoints.size()*sizeof(MyVertex), &m_vertexPoints, GL_DYNAMIC_DRAW);
m_vertexPoints.clear(); //the culprit?

Tested on Intel(R) Pentium(R) Silver J5040 CPU @ 2.00GHz (IGP), Linux Mint 20.1
but then calling after the first call to glDrawArrays (via call list ‘only’), then this works fine.
You can delete or otherwise invalidate the CPU-side data as soon as
Whatever your problem is, it isn’t with the code shown above.
