how does the "trail" look like

SUMMARY
Closing window with ALT-F4 when I made it transparent by dragging makes it impossible to remove the trail of the window

STEPS TO REPRODUCE
1. Enable half-transparency in KDE setting, to make windows transparent when you drag them around
2. Drag any window to make then transparent
3. Use ALT-F4 to close then while dragging

OBSERVED RESULT
"trail" of window is left behind

EXPECTED RESULT
It should not leave the trail

Looks like the distro's Qt backport collection may be out of date.
