CTRL+SHIFT+??? also changes language, when just CTRL+SHIFT should do it [duplicate]

Just moved from Unity to GNOME and faced such problem:
I change keyboard layouts by Ctrl+Shift. Often use console and when I press Ctrl+Shift+C/V (or any other combinations, where there are Ctrl and Shift), GNOME also changes keyboard layout language.

In Unity, and in Windows, the computer normally waits whether I add to the combination any additional keys or release at least one of the keys (Ctrl/Shift) in order to change the language. GNOME, in my case, changes the language immediately once Ctrl+Shift are pressed.

I have Ubuntu GNOME 16.04, x64 (Fresh installation, downloaded from https://ubuntugnome.org)

Can anyone suggest how to fix this?

Solution 1:

It is known ugly bug - see launchpad bug 1245473.

I'm writing this from Ubuntu 16.04.3 LTS with MATE DE. It does not have this problem.
I'm using Ctrl+Shift layout switcher for English and Russian languages.
I see no interference here.

But MATE on Ubuntu 17.10 and 18.04 LTS has this problem - see other launchpad bug 1720364.

My complete position is written in comment 528 for bug 1218322 at launchpad.

Solution 2:

As a workaround you may set another key combination instead of Ctrl+Shift to switch keyboard layouts which is not used in console.
For example you may try Ctrl+Super or Ctrl+Shift+Super.
