GUI becomes totally unresponsive when streaming a single headstage's worth of npx data

The workflow consists of the onix source the LFP viewer. LFP viewer shows the scroll line but I cannot click any buttons in the GUI or stop acquisition.

The dev team seems to think that this issue goes away when the the LFP viewer is compiled in release mode. Maybe so, but why? What is the non-optimized part of this code that would cause such catastrophic behavior?

It appears to be an issue with the GPU. When I switch to the CPU rendering method (View → Renderer → Software (CPU)) there is far less of a performance hit. There is still a slight delay between scrolling and the LFP viewer updating the view, but it is not severe enough to lock the whole UI for minutes at a time. Based on testing, and conversations with the dev team, this does not appear to be an issue with the plugin itself, but rather the hardware (e.g., GPU) we are running the system on.
