SUMMARY
On reproducing the crash for bug 469908 several times, I found my non-maximized
windows are moving. It seems, the window decorations are not properly accounted
for. So for each crash, the window jumps up / left by the thickness of the
title-bar / its dragable border.
STEPS TO REPRODUCE
1. Setup a screen with some unmaximized windows/dialogs (e.g. Konsole,
KMahjongg, KNotes, ...)
2. take first screenshot
3. kill -s 11 $(pidof kwin_x11)
4. take second screenshot
OBSERVED RESULT
The screenshots show some movement shifting some windows / dialogs potentially
off screen
EXPECTED RESULT
Don't move.

ADDITIONAL INFORMATION
- KNotes seems immune, as it doesn't have decorations.
- Also Signal seems protected, as I have a window-rule to set it's position on
initialization.
- And finally maximized windows likely ignore positioning and just set their
state as maximized requesting all the screen.
