Just like Michael, I have this problem too on Ubuntu 16.04 64bit on a Lenovo ThinkPad E560, particularly in Firefox Quantum 58.0.2, on some form text inputs. I haven't encountered this issue anywhere else. The workaround proposed by Antanas on #2 doesn't work for me.

Is really someone looking into this?
