I don't know since I'm still using orca 3.4.2-2 from Debian/unstable
with all kinds of desktops. Using the correct environment variables and
startup sequence, orca will work fine with LXDE, KDE or Gnome up to 3.8,
apart from the two annoying bugs I mentioned before. Plain GTK2 as well
as GTK3 work fine. I did not get a chance to test orca 3.10, but if
someone provides a preliminary package, I can try. :-)

Orca really changes the keyboard layout, so if you has configured your
Xorg to use a german keytable, orca will reset this to english. The most
prominent visible difference is that y and z are swapped on the german
keyboard (qwertz instead of qwerty).
You will only be able to see this behavior if you had set a different
keyboard, other than english, for your desktop. The keyboard layout
change is global and not related to a specific window accessed by orca.
And it's not just the "xmodmap" call in orca.py, which I already removed.

You will need a .xsession where you start "orca -n" prior to your
desktop session ("startlxde", for example), and before both, set
environment variables for enabling accessibility accordingly:
export SAL_USE_VCLPLUGIN="gtk" GTK_MODULES="gail:atk-bridge" GNOME_ACCESSIBILITY=1 QT_ACCESSIBILITY=1
Despite an occasional message of some gnome programs that "GTK2 and GTK3
accessibility" would "not be supported at the same time", it works with
both.

See my prior post about speech-dispatcher configuration as a system-wide
service.
