You might need to adjust parameter opencl_memory_headroom in
darktablerc.
Thanks to remember me to do this. Could you please tell me the exact
name of the variable(s) to change?

Your output of nvidia-smi could indicate leaking memory. About 700MB of
VRAM is used which seems high to me. However, I don't know the
requirements of xfwm4. Maybe it's normal. If this memory usage is stable
you will need to set opencl_memory_headroom to 700 or 800.
