Slanted remote vnc desktop
SUMMARY
Nearly all [older?] clients display the remote system "slanted".
STEPS TO REPRODUCE
1. Using built in Desktop Sharing (with unattended access, if that matters)
2. Connect from almost any older client. (Using KRDC from Debian stable
reproduces this for me for instance, when connecting to the Debian Testing
system.)
2b. KRDC in Debian TESTING seems to be working (when I krdc back to myself),
so it seems there's some compatibility issue.
OBSERVED RESULT
[Slanting: See screenshot]
Each line seems 1 or more pixels shifted to the left.
[Scale] xtigervncviewer (from Deb-Stable) refuses to scale, as do some other
clients. I have tested this only with a few and don't have good data on it
right now. Though sloped, scaling does seem to be working with krdc(stable) ->
krfb (testing)
EXPECTED RESULT
:) Display should be rectangle'ish, not parallelogram'ish :)

ADDITIONAL INFORMATION
Android VNC viewer (from RealVNC) works. In debian-stable, the only client I've
found, that doesn't cause the tilt, is xtigervncviewer.
