With the new version, I thought this might work... Unfortunately, the VNC clients packed with the Raspbian image repositories are performing poorly, with one exception - ssvnc (after some tweaking), but the programs last update was in 2011... and I want to change F8 to something else...
Then, here is the long story short.
I remembered that Thinlinc is using TigerVNC in their product and they have ARMv7 hard-fload version on their download page: https://www.cendio.com/thinlinc/download . I have downloaded the Linux Dynamic package for this purpose. After extracting the package, one simply needs to run this binary:
tl-4.3.0-4538-client-linux-dynamic-armhf/lib/tlclient/vncviewer
Enjoy!
Thanks to the ThinLinc team.
Update 2015.03.27: RealVNC binaries for Raspberry PI can be downloaded from the software developer's page http://www.realvnc.com/download/viewer/
