Cannot use keyboard in Google Chrome app

**Update (20/10/2014)** After a routine update of installed apps everything seems to be working as expected. I suspect that updating the LG Keyboard app (which came with the phone) did the trick. **Original** I have a rooted European LG G3 32 GB on KitKat 4.4.2. Up until a day ago I could happily browse the internet using the Google Chrome app. However now I am able to do everything but typing using the keyboard. I can press on links, go into settings and use voice control to browse but I cannot type anything. When I press on the search bar, the keyboard shows up as usual but it is completely inresponsive. And if I keep on pressing the keyboard the app freezes. I had to press the back/home buttons over ten times to leave the app. I have tried clearing both cache and app data, force stopping the app, reboot, uninstall updates and reinstall updates but no joy. Next I tried Chrome Beta, but it's all the same. I have also tried the stock android browser and Dolphin, those two do work. So my issue seems to be concerning the Google browsers only. What could I do to fix this malfunctioning?
