Uhm... I did. That’s the whole point of this mail; the one I switched to
shows this problem.

That would technically work for me, but it introduces a bit of lag and
I prefer icons, for they are faster to recognise than a miniature that
is changing constantly.

What I do use occasionally is the present windows (a.k.a. Exposé)
effect because of its neat quick-filter.

Aurora is the not-yet-published beta, innit? I suppose then you’re using
an out-of-tree ebuild, because it’s not in portage and you’re speaking
of use flags.

That is my usual approach at debugging weird behaviour, also to rule out
any left-over cruft in my user’s config from previous KDE versions.
(Albeit that this particular install and its home dir is practically
new, I only synchronise select files and dirs between machines with

A new test user has the issue just the same.

I did this in the past... I think it was a font rendering issue. For
that I actually bisected my config dir by clearing it and then doing it
Newton-style -- always adding half of the remaining files until the
issue cropped and then removing half of what I last added until it was
gone again.

Well as I said, I compared the package contents and the arch package
just installed more icons (not only until 128×128, as Gentoo does these
days). I might have to look at it again.
