Applications using Clutter freeze with warning "pick() of an actor is not correctly ...... or ..... error in the glReadPixels() > implementation of the GL driver"

Reported by: teabag Owned by:
Priority: major Component: 3D support
Version: VirtualBox 4.0.4 Keywords:
Cc: Guest type: Linux
Host type: Linux


System configuration:
Virtual Box 4.0.4
Host: Ubuntu 10.04
Guest: Meego 1.1 netbook -

XFCE Desktop Environment
Clutter version 1.4

After installing the VirtualBox Guest additions, and enabling 3D acceleration, we get the below message on launching a clutter based application:

launcher:929): Clutter-WARNING **: The required ID of 4194304 does not refer to
an existing actor; this usually implies that the pick() of an actor is not
correctly  implemented or that there is an error in the glReadPixels()
implementation of the GL driver.

Observed behaviour: The observed effect is that the clutter stage freezes. Occasionally the clutter application works properly without freezing or throwing up the Clutter-Warning.

(Also observed in VirtualBox 4.0 version)

Which clutter application are you running?

comment:2 Changed 3 years ago by teabag

This is an application developed internally by my team. It works properly with 3D acceleration disabled on the VirtualBox, but throws up the above warning on enabling 3D.
