I have two computers running System76's Pop!_OS; a desktop machine with nvidia graphics and a laptop with intel xe graphics. On the desktop machine, draw works ok; but, on the laptop, every time I issue a 3D draw command (vinit, vdisplay, vsetdispmode, etc.) the terminal window hangs until I move the mouse into the 3D view window (or alt-tab the focus to it), then the 3D window updates and I get the next prompt in the terminal. I presume that the nvidia driver is delivering an event that the xe/Mesa driver isn't. Has anyone else seen this behavior? Is there an easy fix?
Thanks,
Allen
