I’m experimenting with openGL and MXJ, rendered in a maxforlive device.

I’ve slightly modified a Jitter example patch (jitter-examples/java/javagltest-example.maxpat ), pasted it into a new max midi device in Live, and I consistently get Live to crash, here’s how :

- in live, have a couple of tracks created in session view
- load the created device, let’s say on the first MIDI track
- let the device do its display job by turning on the qmetro
- select a different track
- select the first MIDI track. OK no problem at this point.
- select a different track
- select the first MIDI track again
- the whole device doesn’t display (white rectangle instead), and Live crashes.

The only modification I made from the original example is to render on a jit.pwindow instead of a floating jit.window. I’m attaching the modified patcher and M4L device.

Does that sound like a familiar problem? The patcher runs just fine in max alone.

Thank you for any hint!
