Comment 59 for bug 1807056

On Ubuntu 20.04, I have similar problem. Actually, I met this problem since 19.10, however in 19.04, it was fine.

My default GUI env is GNOME, and I switched to KDE recently but the problem still occur sometimes.

This problem is a little bit different from other people in these aspects.

1. This problem not only happen in gnome-shell. it happens almost every where, especially when you type in a textbox. For example, in chrome and pycharm, I met the similar problem. Which indicates that this bug is a general problem.

2. When my keyboard is freezing, I cannot type in the TEXTBOX. however, other part of keyboard still work such as Capslock and Super(Meta) button etc. Simply speaking, when the keyboard is freezing, I can still push META button to present all windows, however I CANNOT type anything to input in the TEXTBOX.
