OpenGL issue: GL_INVALID_OPERATION
Problem
Zivid software is not able to capture, and outputs the following error message:
Error
Error: An error occurred:
CameraImageItem: "ptr = glMapBuffer(GL_PIXEL_UNPACK_BUFFER, GL_WRITE_ONLY)" failed! (OpenGL error: GL_INVALID_OPERATION)
Potential cause
When using Linux 5.8 kernel (released with Ubuntu 20.04.2) with Intel GPU as rendering device, Zivid Studio and Visualizer can give OpenGL errors like the one above when displaying the point cloud.
Note
Ubuntu 20.04 only
Potential solution
Downgrade to the LTS(stable) base Linux kernel 5.4.
