The only relevant log messages I can see there are:
Impossible to set scaling on crtc 65 to 1.000000, error id 2 Window manager warning: Scalig CRTC 65 at 1.000000 failed
which is a bug in Xdcv as detailed in comment #16. Remember to keep fractional scaling turned off.
To see if it's possible to work around that bug, you might like to try the "vv4" build:

I'm not yet sure that log message and the Xdcv bug that causes it is critical to fixing this bug 2020782 though.
