Description Alexander Mentyu 2018-04-03 14:40:00 UTC 
Steps:
1. Launch XWayland app.
2. Press and hold left mouse button on app window - but not on the app titlebar.
3. Without moving of the app window - release the mouse button.
4. Take a look at top left corner with the notification.

Tried with Chromium, Firefox, VLC.

The notification is displayed almost every time.

Comment 1 Martin Flöser 2018-04-03 17:07:05 UTC 
That is correct: the apps grab the mouse and KWin reacts accordingly.
Comment 2 Xu Zhao 2018-05-20 23:27:46 UTC 
Is there a way to disable the notification in kwin?

Here is a workaround that I found today.
Change the /usr/share/kwin/onscreennotification/plasma/main.qml:
visible: osd.visible to:
visible: osd.invisible

can hide this and all osd notifications.

Could you please elaborate on that? I still can move my pointer wherever I want, and as far as I can see it isn't confined to the current window at all.
And why does it affect only XWayland windows if it is correct behavior?

In this particular case this notification seems to be at least misleading.

There are upcoming changes to pointer grabbing in next Plasma.
