Description Nate Graham 2018-02-20 03:48:19 UTC

See attached screenshot. The cursor was over the Kate window, and the Konsole window was partially overlapping the Kate window. "Window Under Cursor" mode undesirably captured the overlapping part of the Konsole window, too. 100% reproducible when any case of Window X partially overlapping window Y, and you take a screenshot of window Y with Window Under Cursor mode.

Comment 2 Kai Uwe Broulik 2018-02-20 08:57:11 UTC

Can you check whether that's actually Spectacle or a bug in KWin's screenshotForWindow DBus grabber?

Comment 3 null 2018-02-20 14:44:48 UTC

Testing in IceWM the behaviour is the same.

Probably NOTABUG, but might be a usability issue. See https://phabricator.kde.org/D10673#210005.

Comment 4 Nate Graham 2018-02-20 14:46:11 UTC

Hmm, yeah, possibly. I would be strongly in favor of collapsing the two modes into one, if we can do it without losing features.

Comment 5 Nate Graham 2018-02-21 04:58:25 UTC

Tracking that in https://phabricator.kde.org/T8033

Comment 6 Viorel-Cătălin Răpițeanu 2019-02-12 06:43:14 UTC

Putting this ticket on confirmed as it's still reproducing using the master branches. The resolution of this will depend of T8033.

Comment 9 Antonio Prcela 2021-11-01 16:13:10 UTC

Steps to reproduce:
Open Spectacle, set to 'Window under cursor', uncheck 'Capture the current pop-up only'.
Click on 'Take a New Screenshot'.
----
When checking 'Capture the current pop-up only', it doesn't include an overlapping window.

When using META+CTRL+Print, it also doesn't include an overlapping window.
Launching via shortcut doesn't check for 'mCaptureTransientOnly'.
Whereas launching via the button, checks 'mCaptureTransientOnly':

Just stumbled on this bug while searching if something was already reported...

I can't reproduce this in 24.12. Can you guys check. It might be resolved.

Comment 11 Nate Graham 2025-01-06 21:54:57 UTC

Yup, definitely fixed now. Thanks for following up!
