Somehow with recent master, Notifications animate from top to bottom and it is quite annoying/distracting. Reproducible: Always
Interesting, there were no changes in notifications code at all, so must be something else that has influence on it.
Ok I've spent considerable amount of time bisecting things all the way to 5.4.0/5.14, but it happens even there, so I believe this is a Qt change (I had 5.4 before and couldn't reproduce, now with 5.5.x I can). I'll try to change the location-setting code to be better.

[notifications] Rework the notifications positioning a bit The notifications popup positioning recently regressed by some other changes (looks like Qt) and the popups would fly across the screen. The proper solution is using KWin effect but given how close the release is, this needs to be dealt with in a different way. The main problem is calculating the initial popup size because as long as the Dialog is invisible, it has an incorrect geometry, so it needs to be positioned right after it's being displayed. The Dialog however gets the sizes even later, so the code now calls a slot from Dialog that ensures the sizes are correct before the initial placement on screen. It's not ideal but I'm out of ideas otherwise. Plus it should be only temporary until the KWin effect will replace it. Besides that, it moves the custom position handling from the QML into the C++ applet class, making it easier.
