Comment 17 for bug 1633721

I get the exact same error. Like comment #15 says the workarounds from comment #5 and #9 work but only for certain text input fields i.e. trying to input my password for administrative activity popups is almost impossible. Same with inputting the wi-fi password. I have to resort to using my browser or something to type my password in and the copy and paste it. Also I have been getting graphical errors (wallpaper stretching) that also can be temporarily fixed by using `killall plasmashell` and then `plasmashell` which seems to be related to this. I made a post about it on askubuntu located here http://askubuntu.com/questions/878815/slight-issue-with-wallpaper-kde-plasma-5-ubuntu-16-04
