Hi Aleix, I would try reproducing it with one of the Qt examples, try the ones in qtbase/examples/widgets for instance.
Otherwise, WAYLAND_DEBUG logs might have some clues as to what's happening.

It happens randomly and I'm not even sure that it's Qt's fault anymore, but I wouldn't discard it either. Initially I thought it would be [1] but it got fixed and I still get it. An easy way to trigger the problem is by using krunner. Just open it, type something until you get some results, press Escape. Sometimes it needs doing a couple of times. With yakuake it can be done as well by pressing its key combination a couple of times not even that quickly. Any ideas what this could be? Aleix [1] https://bugreports.qt.io/browse/QTBUG-76124
