Description Liarus1001 2025-03-22 20:29:41 UTC

SUMMARY

Using the "Capture Rectangular Region" over an xwayland app such as game in my case, makes it so spectacle doesn't copy the image properly into the clipboard, as an extra note, what is strange is that using meta + v to see the clipboard history, the captured images are present, however they cannot be pasted in any other software, like krita, discord, or anywhere else.

Other capture methods such as "Capture Active window" or "Capture entire desktop" work perfectly fine, only "Capture Rectangular Region" has that behavhior.

STEPS TO REPRODUCE
1. Have a xwayland window open (a game as an example)
2. Use the shortcut to trigger "Capture Rectangular Region"
3. Try to copy / paste the image in any software that supports pasting images.

OBSERVED RESULT

The captured images cannot be pasted anywhere.

EXPECTED RESULT

The captured images should paste just like any other capture methods.

ADDITIONAL INFORMATION

This bug used to be inconsistant in the past, sometimes it happened, sometimes it didn't, recently it started just, not working at all (sorry i did not take note of the KDE updates that completely broke it, as i simply got used to dealing with the bug by just capturing the entire window/saving the image and uploading it instead)

Hi - a couple of questions to hopefully help narrow things down:

* Does pasting into a different application, like KolourPaint, LibreOffice Writer, etc. work?
* Does activating a different item from the clipboard history, then re-activating the screenshot, enable it to be pasted? (Looking at https://bugs.kde.org/show_bug.cgi?id=500366 )

Thanks!

- Does pasting into a different application, like KolourPaint, LibreOffice

It does not, though it's quite inconsistant, sometimes it does work, but most of the time it does not, sorry i know this is vague, but i'm genuinely not able to find a pattern.

- Does activating a different item from the clipboard history, then re-activating the screenshot, enable it to be pasted? (Looking at https://bugs.kde.org/show_bug.cgi?id=500366 )

Yes it does, i can reproduce this

Thanks! It sounds like it's likely a connected underlying issue, so I'm merging this together with that other existing report since some exploration has already been done there.

Hopefully bringing together more examples of how it manifests can help with eventually identifying a solution :-)
