VNC Screen Repaint Delay
|Reported by:||kihjin||Owned by:|
|Version:||VirtualBox 4.0.8||Keywords:||OSE VNC|
If I reconnect to a system that has been online for a few hours, the screen is usually completely black. Clicking around on the screen slowly causes it to invalidate regions and cause paint updates. The host and guest systems are recent releases of ubuntu. This behavior occurs regardless of the VNC client used. It was not a problem in 3.2.12. The guest system has Guest additions 4.0.8 installed, but I have seen this behavior occur with guest additions 3.2.10 even on a 4.0.8 system.
This is NOT a screen saver - that is completed removed from the system and isn't even running as a process. Xorg doesn't report any issues on the guest. I have diff'd the FramebufferVNC code between 4.0.8 and 3.2.12 and there isn't any significant difference to explain this behavior.
Also, the display is configured to never go to sleep in ubuntu.
