virtualbox.org

I've found that by changing the VM background to the same background as the host creates the illusion that there is no "lag" when dragging the window where normally the guest's background would be visible. However, it's not completely correct because seamless mode doesn't account for the taskbar. I put my taskbar at the top which offsets the guest background.

Ideally I would like to see VB set this automatically but restore any native background in the VM when exiting seamless mode.

Just a tweak idea to improve seamless mode.

Very cool idea

Moved to the general forum so it can be spotted by more people.
