Thanks for the report. Part of this is known and is caused by missing page flip functionality in EVDI, which we are aware of and are working on it. Remaining traces show something else, that's probably specific to changes in 4.4 line.
What is your distro and graphics environment?

Thanks,
Michal

Quick question - what steps did you follow to get it working with the 4.4 kernel? Or was it just a matter of running the 3.x kernel install.run?

I just unpack the files and move the binary's into an /opt folder and have a custom rc-d startup script i wrote to start the manager.
