Lazarus QT5 doesn't register key strokes

Hey Guys, i got some very weird problem on the latest Lazarus QT5 version 2.0.12 from manjaro repositories. The source editor simply doesn’t register any key strokes anymore. It was working fine yesterday. The same problem doesn’t happen on the GTK2 lazarus interface, so i guess there’s something related to qt5.

Here is a small video showing the problem.
