24-bit color depth warnings with Windows 7 + Guest Addition

Reported by: jimav Owned by:
Priority: minor Component: guest additions
Version: VirtualBox 2.2.0 Keywords:
Cc: Guest type: Windows
Host type: Linux


Updated to VBox 2.2 and now a pop-up warning appears every time a Windows 7 VM is started saying that the virtual display is set to 24 bit color depth but should be set to 32.

However, Windows 7 thinks the color depth is 32, as indicated by the following:

Right-click desktop->Screen Resolution
Click <Advanced settings>
Click <List All Modes>
The highlighted mode is "1400 by 1050, True Color (32 bit), 60 Hertz"

So it seems like either Windows 7 is reporting the wrong mode (the resolution is correct, at least), or the Guest Additions and/or Vbox is incorrectly giving this warning.

Re-installing the new Guest Additions and rebooting the guest did not fix the problem.
