--- Comment #17 from Ash Blake <telepath...@tutanota.com> ---
This time, however, it seems EffectWindow was not completely destroyed.
Unlike in the last crash, the data inside EffectWindow is not complete garbage.
For instance, the addresses in toplevel and EffectWindow::Private pointers look
more sensible, dataMap contains valid pointers to QHashData::shared_null, and
x11Client is true.
(gdb) p *(EffectWindowImpl*)(entry.i->key)
$10 = {
<KWin::EffectWindow> = {
<QObject> = {<No data fields>},
members of KWin::EffectWindow:
static staticMetaObject = {
