We have an application where there are problems with the video quality, specifically
vertical edges show jagged edges or tearing when there is horizontal motion. This is a ptz
security system, so this is quite noticeable to the customer.
Currently the system runs with just Xorg running, the application creates a framework and
renders video into it using xvimagesink.
While investigating I reflashed the unit to the factory image and ran the application with the
ubuntu unity desktop running, and the quality was much better. Reverting back to no window manager
and the problem came back.
The Xorg command lines are the same, the Xorg log files are nearly identical.
The application is exactly the same.
Any ideas why running with the unity desktop running would result in smoother video?
Thanks in Advance
