Please try to report your experience using `report-emacs-bug'. Eli Z., who is the developer working on bidi support, would _very_ much appreciate knowing about any such issues. It's not obvious to him what might not work well, unless he receives a bug report. The more specific you can be, the better. > Do you have any other useful emacs24 settings? Nope, not yet. There have been quite a few changes made to the way (where, how) buffers get displayed, but that development seems to still be in flux (redefinition). If you experience odd behavior wrt buffer display, please report it as a bug. As always, if it turns out that there is no bug, the Emacs developers will be happy to let you know. When in doubt, report something as a bug, to provide them the info. They can then sort things out.
