I have the same issue between two Macminis both running mountail lion 10.8.4
It affects mostly firefox. I can move the FF window and it updates everything. Otherwise,
only where I move the mouse. Very disconcerting

This is what I am expriencing, sharing the screen of my brand new headless mac-mini (2012, 16GB RAM) to my other mac-mini (2010, 16GB)
It happens to Firefox, VMware and other apps, but not all.
The symptom is that basically that the screen only redraws where the mouse is moved, unless I move the whole application window.
I tried the tricks with the miniDP-VGA dongle (resistor across pins red/red-gnd), the miniDP-DVI (1kOhm across pins 14+16) and all possible settings in the screen sharing etc.
It just doesn not work.
Using Chicken of the VNC as VNC client is no better, it exhibits the same issues.
This needs to be fixed

I'm getting this exact problem too.
I originally had a Mac Pro server and didn't have this problem until I moved to a Mac Mini server. The Mac Mini was a fresh install restored from a Time Machine image of the Mac Pro.
I have tried installing a combo update and the usual repairs/fixes but to no avail. The only thing that stops the problem is running Firefox in safe mode (via Help / 'Restart with Add-ons Disabled...')
Sounds like it's a Mac Mini specific issue.

I've worked out a solution...
If you run ScreenResX on your MacMini and set up a resolution profile to match your remote machine (ie. MacBook Air - 1366 x 768) then the remote res is the same as the local res and there is no graphical corruption in Firefox.
Screen Sharing will be much more responsive too as it doesn't have to scale the pixels on the fly to your remote machine.
This solved ALL of my Screen Sharing graphic corruption problems (incl. Firefox)
Here's an example of the profiles I set up in ScreenResX on my MacMini server to match my client screens...

I did try ScreenResX but was in a hurry and didn't have time to get it set up properly so I abandoned it pretty quickly. However, I wanted to update the thread to say the problem disappeared when I updated the MacMini to Mavericks. The mouse control is really slow, but FF works again.
