I'm not sure we (ie. Martin) can even delete it:
https://www.bugzilla.org/docs/2.20/html/faq.html#faq-phb-deletebugs

If it's critical, we got to bounce sysadmins on this (no promise they can,
though)

"xdotool windowmap 0x1a00100"

Works. And it gets my windows back and they are working. 

I'll bodge up a script that will keep me happy until Qt5 is patched/I have said
patch.

Icons trimmed from xprop output. 

Tested with Openbox. Same result.. My apologies for lodging it against the
Kwin. It does appear to be similar to the Qt5 issue.

Also, is somebody able to redact some of that... I left names in window titles
as I wasn't thinking.

No it's fine. It's not critical.

check the status of the processes with lost windows (stopped?) and dump
"xwininfo -id " and "xprop -id " for them.

As long as only Qt5 clients are affected - and given the occasion, this is
probably a weird outcome of bug #341497 (in that client, apparently KWin didn't
crash)

I'm quite certain that this is Qt's fault and not KWin's fault. So please run
for testing another window manager (e.g. openbox) and try again.
