I use the newest Virtualbox on a Windows 7 x64 Host. Guest OS is Windows XP 32bit. I use it in seamless mode.

The Screens are set like this:
Second monitor <- Main monitor

When I move a application windows from the main monitor to the second monitor and back, the second monitor isn't refreshed.
I can move a second application, and after moving back from the second monitor to the first monitor, both applications are somehow visable.
Refreshing doesn't work properly.

I tried this on two different computers (ATI and Intel HD graphic cards). Both with the same result.

Please look at the attached photo.

Seamless with 3D acceleration does not work properly and never has. See Chapter 14 Known limitations in your VirtualBox users manual.

Same problem with deaktivated 3D acceleration.

Did you reinstall the GAs after deactivating 3D in the settings?

I tried re-installing GAs, no success. Same problem...

Don't know, if it helps you, but refer to

And the hint to make the colours-profiles on both monitors removed the problem with 4.2.6 with 10.6.8
