Comment 244 for bug 36812

After the next update of the package "xserver-xorg-input-evdev-hwe-16.04" (with dependencies) from the version "1: 2.10.2-1ubuntu1 ~ 16.04.1" to the version "1: 2.10.5-1ubuntu1 ~ 16.04.1 ", in the KDE shell, the language switch does not happen when the keys are released, but when pressed.

Distributions on which this problem was repeated:
neon-useredition-20171012-1018-amd64
kubuntu-16.04.3-desktop-amd64
kubuntu-17.04-desktop-amd64

Distributions in which there is no such problem:
ubuntu-16.04.3-desktop-amd64
ubuntu-17.04-desktop-amd64 (but there is no such package)

When setting the switch to Ctrl-Shift, you can not quickly select text with the "Ctrl-Shift-Arrows" keys. However, you do not want to have outdated xorg packages. Extremely uncomfortable, help!
