Unfortunately, one of my two screens died two months ago. Due to the shortage/disappearance of 4/3 19" matte screen, I decided to wait for the death of my second screen…
However, I wondering if you ever try to use "Screen Sharing" (⌘K in the Finder, vnc://ip_or_hostname) instead of ARD for the visualization?? It might possible that the bug is not existing within Screen Sharing, and of course you can still use ARD for "advanced" functions (report, install, etc.).
