VirtualBox 5.0 regression: full screen mode with composite manager works incorrectly

Just upgraded to VirtualBox 5.0 (host: Ubuntu 14.04 amd64, guest: Windows). Relevant extension pack and guest additions installed.
PROBLEM: When switching to full screen mode, the VM screen resizes all right to fill the screen, but the screen is dimmed (brightess is reduced). Looks similar to the effect when you pause the VM, but not quite.
INVESTIGATION: I narrowed down the problem to compton, a compositor for X11. When compton is killed, the fullscreen mode works fine.
Previously, with VirtualBox 4.3.30 (and many versions before that), fullscreen mode used to work correctly with compton.
