This bug was reported against an outdated version of KWin. We have made many
changes since the. 
If the issue persists in newer versions can you reopen the bug report updating
the version number.

I can confirm that this bug is caused by Qt5 using XInput2. Disabling xinput2
support in Qt fixes it. (Also on wayland everything works fine.)

Yes, it also happens in kate.

The problem does seem to be limited to Qt5 apps, though I haven't tried them
ALL :) .

I assume that you see this with all Qt 5 applications? E.g. also kwrite/kate?

My idea is that this is related to Qt 5 using Xinput 2 for scrolling, thus KWin
does not intercept the events properly anymore.
