Comment (by ericvanblokland@…):

 I've read the original tracking ticket but did not see a clear reference
 to this issue and because the heavy development I was unsure about the
 status of the problems you mentioned there.

 Do I understand correctly you're saying: "install the splitted desktop
 backend and you're good to go!"?

 The current trunk of mythtv is pretty unstable for me while my system
 appears to be very stable over all. The mythtv crashes never relate to
 video playback whatsoever. It tends to happen when changing settings,
 plugin in removable storage, all that kind of stuff.

 I've got some info for you regarding mythv+linux+ati+fglrx, since it's a
 pain in the ass. Some stuff you will already know, others might be new and
 help save you some time.

 - The fglrx drivers continue to appear to be hack. Video will tear unless
 you enable "Tear Free" in amdcccle. Enabling this option locks up the GPU
 on certain HD4XXX chips. Login remotely and run "aticonfig
 --del-pcs-key=DDX,EnableTearFreeDesktop" to disable this option again.


 - fglrx has an issue with paint order when using OpenGL. The UI will be
 painted over video playback. You've fixed this in your VAAPI
 implementation (yay!). However, setup menus and wizards are still
 inaccessible. ATI users are adviced to use "export
 LIBGL_ALWAYS_INDIRECT=true" which degrades performance but makes menus
 visible again. With this option on the UI will be painted over the video
 when using VAAPI.
