VRDP screen flicker

Reported by: tomatoman Owned by:
Priority: major Component: RDP
Version: VirtualBox 2.2.4 Keywords: flicker
Cc: Guest type: Windows
Host type: Linux

Description

Version 2.2.4 on Ubuntu 9.04 64 bit host running Windows XP 32 bit guest. On host there is no anomaly - everything is as expected (and same as in version 2.2.2). I start the guest. When I connect from a Windows XP machine via Remote Desktop Connection (default port, NULL authentication), the following happens: The screen appears normally with the Windows login prompt. Once I get past the login prompt and the desktop appears, the screen starts flickering on the remotely connected machine as well as on the Ubuntu host. The same setup was working perfectly in version 2.2.2. The 2.2.4 changelog states that a rare incorrect screen update was fixed - in my case an incorrect screen update is happening now.

Please attach the VBox.log file for the flickering VM run.

I turned off Compiz on the host and the flicker is gone. While the problem with the flicker still exists, in all fairness the host does not need to run Compiz, so the priority could be downgraded. Interestingly, I turned off Compiz because it also interferes with VNC - except in VNC the client sees only the initial screen, no updates after that.
