The article suggestions didn't fix the problem?
You can send Apple feedback, but they obviously are aware of the problem. They won't answer you.

I'm seeing this on a headless Mac mini Server when trying to use Screen Sharing to another Mac on the same local network. I remote into the server via TeamViewer or even when onsite using Apple Remote Desktop. NONE of the fixes in the referenced article apply. All Macs are running 10.8.4, none of the Macs are set to log out after inactivity. It's completely repeatable and nearly impossible to work around. Dragging a file over the window (just don't let go or it will copy) refreshes the screen, but it immediately freezes again so no updates can be seen.

Other people have reported problems when the Mac mini is headless. If you have a way to connect an external monitor to the Mac mini, it might be worth a try.
