Also: sometimes the task switcher or just its background blur momentarily
appears in the screen centre.

Observed on plasma 5.12.

It centers for me on the first invocation sometimes, but then the entries are
not highlighted. On the next invocation, it appears at the top left.

Sometimes after changing of visualization in Task Switcher - it appears in the
center (looks like more likely after changing into 'Grid' visualization - using
it - and changing back into 'Breeze Dark' for example) - and also after some
time of changing of various visualizations - they all starting to show up in
the center

I investigated this problem a bit further. At this late position

https://phabricator.kde.org/source/kwin/browse/master/tabbox/tabboxhandler.cpp;184b490c78a3a3e5ae25105c08b19fc375e8c64c$395

the correct d->window()->x() value is still set (in my case to 498). Some time
later it gets reset to 0 for some reason. For example in the delayed call to
initHighlightWindows it is already 0.

If you fix this, I'll be really close to being able to make the switch to
Wayland full time! :)
