I'm a old user of kde and unstable debian and I was a happy user until kde 5.8.
Since the upgrade to 5.8 and beyond, my keyboard works "slow". A example: when I press Alt+F2, and shows the runner, I type any thing and not happens. Some time ago, appears one or other letter typed.
I prepared a USB with a live debian and tried again. When I try to do the test, works fine. How my language is brazilian portuguese and my keyboard is a US layout, I select US with dead keys.
The simple question to select a keyboard, starts my problem. Without this, works fine.
Some idea or suggestion? I haven't idea of how to debug this problem. What can I send to give a better idea?
Since now, thanks by any help.
