Lossy compression of screen?

[monken]

It seems like currently, only lossless compression is supported. I have set up a Linux VM and connect through XRDP from a Windows machine. In parallel, I also use Guacamole (guac-dev.org) to connect to the same host. I usually get better performance out of Guacamole when I'm on a high-latency link (cross atlantic). I attribute this to the lossy compression that Guacamole is using as opposed to the lossless compression from xrdp. Is it possible to tweak the compression algorithm to reduce bandwidth and therefore improve performance over high-latency/low-bandwidth links?
