Bug#1100579: switching the keyboard layout is too slow on gnome on xorg

[Alma Madeleine]

Switching the keyboard layout is too slow for me, too. I use the key combination LeftWin+Space to switch between 4 layouts. During switching, other keystrokes get eaten up. For example, when I switch (from another encoding) to German and immediately start pressing (and releasing) the keys in the top letter row of the keyboard from left to right, skipping the leftmost Tab key, I get

tzuiopü+

The top letter keys in German are “qwertzuiopü+”. So 4 keys, “qwer”, have been eaten away. In testing some real words that I'm used to typing quickly, I get “wing” when typing “following” (5 letters have been eaten) and nothing when typing “usually” (the whole word of 7 letters has been eaten). This issue results in reduced productivity, especially when working in a terminal (xterm, gnome-terminal, …) with file names in a non-Latin encoding, as you have to switch between a Latin layout (for shell commands and their non-filename options) and the alternative non-Latin layout (for file names), sometimes many times a minute.

Please fix this.

I don't care about whether a switching OSD screen pops up, but I do care about seeing the current-layout indicator (for me, in the status area on the right in the top bar).
