Terminal dumps with error messages

[baggepinnen]

From discourse:

Every time i click on the inteface, a bunch of text is printed in the terminal:

[4069:0206/155146.687870:ERROR:buffer_manager.cc(488)] [.DisplayCompositor]GL ERROR :GL_INVALID_OPERATION : glBufferData: <- error from previous GL command

We might have to fix this over in Electron.jl, this presumably occurs because the electron main process shares the stderr with our Julia process. We should probably just redirect that by default.
