Framerate is low. Very low (~0.5 FPS). Like a slideshow for video streaming. Each frame's update traps:

Would it be enough to disable "packed" attribute for structures? Marshall/demarshall code just add/consume data of the requested size direct from/to the fields. No casts / memcpy. Chunks are fine too?

I've added hardcoded keymaps for US layout using keymaps.csv file. It looks a little ugly.
