    Just wanted to note that this bug is back in Ubuntu 18.04 LTS GNOME. Tested and confirmed on HP EliteDesk 800 G2 Mini with Unity Engine games, Farm Together for example.

    For anyone like me that was too far along with a project using 2017.4 to upgrade to 2018 without borking your code (major changes from 2017 to 2018), try using the 2017.4.5f1 release.

    Your project upgrade from 2017.4.1f to 2017.4.5f1 should be painless - and it fixes the double-tap keyboard issue with Linux builds.

    Verified this morning (June 21, 2018) with a fresh build and test on Linux Ubuntu 16.04 LTS.

    Same issue causing me problems.
    "engine_ver": "2018.1.0f2"
    Linux system is Ubuntu 16.04 LTS x64

    !!! However, when using the source "Russian" Russian letters are not duplicated

    What about a backport of the fix to 2017.4 (after all it's supposed to be a LTS release and I'd count this as a major bug to be fixed) and 2018.1 as 2018.2 will probably stay in beta for a while?
