90% sure it's the new pager.
I've seen this before on an applet which set the layout hints based on the size
of the item - which then forces the panel (the grid layout in the log) to get
stuck in a loop.
There is code that sets the nuber. rows/columns based on the size of the
applet, and then that updates the rowHeight which in turn sets the applet size.
As i imagine you need to have exactly the correct wrong setup to replicate it,
I have 3x1desktops, on two 1920x1080 screens. The pager shows both screens.
I also have:
file:///opt/kde5/share/plasma/plasmoids/org.kde.plasma.pager/contents/ui/main.qml:171:5:
QML Flow: Binding loop detected for property "rowHeight"
which is probably related.
