I got recently a belt that repeats the input characters. It looks like this:

enter image description here

I don't know where it comes from nor how to turn it off. And best uninstall it altogether.

Not only does it annoy me all the time, but also is dangerous as it repeats the password after login (at least after suspend wake up).

What is it and how to get rid of it?

Ubuntu 16.04, LXDE.

Solved. Credits to Ipor Sircer.

run xprop, then click inside that belt. it will show what is that.

$ xprop
WM_TRANSIENT_FOR(WINDOW): window id # 0x3000005
XdndAware(ATOM) = BITMAP
_MOTIF_DRAG_RECEIVER_INFO(_MOTIF_DRAG_RECEIVER_INFO) = 0x6c, 0x0, 0x5, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x10, 0x0, 0x0, 0x0
WM_CLIENT_LEADER(WINDOW): window id # 0x3000005
_MOTIF_WM_HINTS(_MOTIF_WM_HINTS) = 0x2, 0x1, 0x0, 0x0, 0x0
WM_NAME(STRING) = "vokoscreen"
WM_CLASS(STRING) = "vokoscreen", "Vokoscreen"
        Client accepts input or input focus: True
        Initial state is Normal State.
        window id # of group leader: 0x3000005
        user specified location: 0, 756
        program specified location: 0, 756
        user specified size: 3200 by 120
        program specified size: 3200 by 120
        window gravity: NorthWest
WM_CLIENT_MACHINE(STRING) = "tomas-Latitude-E4200"
WM_COMMAND(STRING) = { "vokoscreen" }

The answer lies here:

WM_COMMAND(STRING) = { "vokoscreen" }

The recently installed Vokoscreen. Now I disable the 'Showkey' option, and it's back to normal.
