Version:           4.7 (using KDE 4.7.0) 
OS:                Linux

Since KDE 4.7 ksnapshot captures itself.

Reproducible: Always

Steps to Reproduce:
1. run ksnapshot
2. select "rectangular region"
3. take a new snapshot
4. select a region that overlaps with the ksnapshot windows
5. return

Actual Results:  
ksnapshot window is part of the screenshot

Expected Results:  
ksnapshot window is not part of the screenshot

OpenGL effects might be needed to reproduce this bug.

The bugs are similar. Bug 260725 says the window hides, but because the
screen isn't refreshed fast enough on a non-composited desktop, you are
seeing gray holes.

This bug actually says the window doesn't hide (on a composited
desktop), which means either the snapshot window really isn't hidden, or
the compositor is faster generating the snapshot, than hiding the
window. In the latter case, it would be a KWin bug.

Hi,

the window turns 50% translucient. And also in the screenshot it is
captured 50% translucient. But it's not a matter of time, the window
doesn't hide completely when I wait longer.

Image of Advanced tab in Desktop Efects settings.

Here it shows fadeout (translucent) at some level if desktop effect Fade
is active. After disabling effect it works as expected.

It seems that is some timing issue. 
When timeout is set to 1s it works every time with or without Fade effect.

To test is it issue as suggested in comment #2 I enabled Glide effect and ... 
KSnapshot window was stuck on the screen halfway faded out and deformed. 

In other words screenshot that is used to select part of the screen that
should be copied to image is created before KSnapshot windows is moved
out of the screen.

Suggestion: add an X11 property to the KSnapshot window which KWin uses
to exclude the window from any close window animations.

Since we only repaint 60x a second this could still fail if the snapshot
(just blits the framebuffer) is triggered before the next repaint (by
the window unmapping)

After i figured that the screenshot effect just blits the framebuffer i
first thought about rendering the scene to an offscreen target, omitting
ksnapshot windows or window IDs, or disabling ksnapshot for painting,
cause a full repaint, blit the framebuffer and then re-enable ksnapshot
and cause a final paint.

But then i wondered what if somebody actually wanted to snap the
disappearing ksnapshot (which is part of the scene when the snapshot is
taken)

-> Maybe ksnapshot rather needs "No Delay"/"When KSnapshot window is hidden"/"1 
sec"/2 sec"/...?
Where the "When KSnapshot window is hidden" entry requires the screenshot 
effect to be running.

The screenshot effect would then emit a dbus signal whenever the
ksnapshot window is ::windowDeleted() and ksnapshot can take that to
safely trigger a screenshot.

Occurs for me always in 4.11.2 when using "Freehand region":

* Set capture mode to "Freehand region"
* Set Snapshot delay to "No delay"
* Press "Take a New Snapshot"
* Ksnapshot window appears semi-transparent (and left on captured image)

I have "Fade" window hiding effect enabled.
