Can you get the same or at least similar tearing on Brazos with
Option "SwapbuffersWait" "off"
With this option I started to have tearing on Brazos. A bit different than reported on Kabini: it is present randomly on whole screen.
or
Option "AccelMethod" "glamor"
With this option I started to have tearing on Brazos almost exactly the same like on Kabini.
in xorg.conf? If yes, the problem is that page flipping cannot be used for the MythTV window, most likely because its dimensions do not match the X11 screen dimensions.
MythTV works here in full-screen. DI (also 2xHW) works OK on Brazos but not on Kabini. As enabling GLAMOR on Brazos causes exactly the same DI issue on Brazos - isn't issue within GLAMOR?
