Deleted text appears again after switching layouts

[DEDan]

Deleted text appears again after switching layouts. Since Ubuntu 13.10 this bug affects me when typing personal message on vk.com. I bugreporting to vk.com support, but they not confirmed this bug on their side. They talked to me that this bug appears since new keyboard indicator was introduces in 13.10.

How to produce:

1. For example, I typed text on wrong layout.
2. Select the typed text with Shift+Home.
3. Deletes the selected text by pressing Del.
4. Immediately switch the layout with Shift+Ctrl (also I tried to use Super+Spacebar)
5. At this step the deleted text is appears.

If at step 4 switch the layout after a second or two, then the text is not appears.

I use Ubuntu 14.10 64-bit + Firefox 33 or Chromium 38.0.2125.111

P.S. There are other problems, such as the editing window of translation on translate.google.com closes at the moment switching the layout.

Can you reproduce the same bug running gnome-shell or any other shell but unity?

[DEDan (zsdedan)]

Yes. I'll try to reproduce this in gnome-shell.

In gnome-shell the same thing happens.

[Andrea Azzarone (azzar1)]

It's unlikely that both gnome-shell and unity contain the cause of the bug. Probably is gtk? Can you test with a qt application?

[DEDan (zsdedan)]

Okay. I tested in firefox on other machine with kubuntu and xubuntu and there is no problem.
Also I tested in webbrowser-app on my system and there is no problem too.

I do not know whether such a reaction of the system to this problem. When switching layouts in the active search box in the "gedit", the search bar disappears. A similar problem occurs in other applications, for example in Evernote Web Clipper addon for Firefox.
