Comment 80 for bug 1244090

(I'm not sure if gnome-settings-daemon is the right product for this bug, but anyway.)

I have things so that pressing ShiftL+ShiftR together will change my keyboard layout.

This works fine. However, when I press that key combination, the current window appears to lose focus and regain it instantly. This is a problem with buggy toolkits (cough) that do things like committing or canceling text entries when they lose/gain focus. For example, GtkTreeView will cancel editing, and Firefox will do funny things depending on which web page has entry widgets in it.

This didn't seem to happen a few Gnome versions ago (maybe it was caused by the switch to ibus?).

Here is the xev log for what it's worth. After the initial ShiftL KeyPress, there is a FocusOut/FocusIn/KeymapNotify.
