OpenGL backend

tomwer uses silx plots behind.

silx can do rendering with two backends:

• matplotlib (Default)

• OpenGL (Enabled by using –opengl-backend option)

By default, the matplotlib backend is used. Although it is less performant than OpenGL, it is more robust.

OpenGL may require a few extra steps to ensure it works correctly over SSH. See the silx OpenGL troubleshooting

When large images are displayed with matplotlib, you may notice lag. In such cases, it is recommended to switch to the OpenGL backend (using the --with-opengl-backend option).
