Does anyone recognize the effect in the linked video?

I'm seeing this occasionally since upgrading my ThinkPad T430s with
Intel graphics (Core i7-3520M) to Fedora 21.  I am running KDE with
desktop effects enabled, and thus far I have only seen this in GTK
applications (Firefox, Thunderbird, and LibreOffice).
