Bug 340929

ksnapshot --version says:

Qt: 4.8.6

“Include window decorations” and “include mouse pointer” are not checked.  The problem manifests regardless of the setting of “Snapshot delay”.

Distribution or compiled from sources?

Graphics system (hardware / driver)?

I'm using the version distributed with Ubuntu 14.04.1 LTS ("trusty").

I will shortly attach a copy of /etc/Xorg.0.log in case that has anything relevant.

Let me know if there is additional information that you need, and if so, how to obtain it.

Could you please try another screenshot utility/command like "import /tmp/tmp.png" from Imagemagick in a console to check if this works properly?

That's a good idea, thanks.  The screenshots produced by imagemagick's `import` command do not have the problem that the KSnapshot snapshots have.  An example is at http://a.pomf.se/abraqw.png .

$ import --version
Version: ImageMagick 6.7.7-10 2014-03-06 Q16 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2012 ImageMagick Studio LLC
Features: OpenMP

I said that the missing strip along the top and left was gray. Actually it seems to be transparent.  What might cause KSnapshot to write an image file with a transparent area?

In your report you say you have the problem only with “Window Under Cursor”, not in the other capture modes of KSnapshot, right?

But your test with imagemagick is a full screen capture, not a capture of a window under the cursor.
Please test again imagemagick's import command but take a snapshot of a not maximized window, eg type "import /tmp/tmp.png" in a not maximized konsole window.

Right.

No, it isn't.  Imagemagick "import" changes the cursor to a plus sign;
then I click on one window, and it captures just that window.

Look again at my Imagemagick capture example:

http://a.pomf.se/abraqw.png

It is a capture of the KSnapshot window, not of the entire screen.
The KSnapshot window at that time happened to contain a thumbnail of a
large capture, but that is not relevant to the test.

Sorry I am running out of Ideas now :-(

Two users reported this on Kubuntu Forums, too: https://www.kubuntuforums.net/showthread.php?67561

Both were using the XRender compositing type. After I asked them to switch to OpenGL, KSnapshot behaved normally. Perhaps others following this bug could try that, too?

System Settings -> Desktop Effects -> Advanced tab -> Compositing type

That did fix the problem for me, thanks very much.

Hello! Sorry to be the bearer of bad news, but this project has been unmaintained for many years and I will be closing this bug. Spectacle is the replacement for ksnapshot now. Please test again and file a new bug for Spectacle if you still have issues. Thank you!

ksnapshot is still in extragear/graphics, it was not moved to unmaintained so far
