SUMMARY Occasionally when taking a screenshot in Spectacle will fail to copy the image to the clipboard. I see it appear in clipboard history but I'm unable to paste it anywhere with Ctrl+V. Other programs that read from the clipboard (GiMP) also cannot see the image data, and any attempt to re-copy it by clicking the entry in the clipboard history fails. STEPS TO REPRODUCE 1. Launch spectacle and take a screenshot of any region of your screen 2. Attempt to paste into a Dolphin window (Crl+V), or in GiMP press Ctrl+Shift+V 3. Repeat until the error occurs OBSERVED RESULT Both Dolphin and GiMP report that the clipboard is empty. EXPECTED RESULT Dolphin should display a prompt to name the file and GiMP should load and display the image.

I also have this issue, and it is so frequent that I have been able to paste a screenshot only a handful of times total over the past 2-3 days (mainly in the form of trying to post screenshots to Discord). The 3rd-party Flameshot software does not have the issue, but I prefer Spectacle's UX when the bug is not occurring. Software Versions: Fedora 42 KDE Edition Plasma 6.5.1 Spectacle 6.5.1 Frameworks 6.19.0 Qt 6.9.3

I have seen this in the recent past: When I have Spectacle set up automatically copy to the clipboard, the screenshot would fail to paste into any app. When I manually clicked "Copy to clipboard" then the thing that's added to the clipboard will paste into apps. However I can't reproduce the issue on current git master of Spectacle and KWin right now.
I can't reproduce the issue depicted in the video with today's git master, but it looks like Spectacle's settings (and also system notifications?) have been customized. Sollace, can you describe the specific settings you're using?

Git commit b71af4e1afcf72b8c9da315dc8d728db70d753c0 by David Edmundson, on behalf of David Redondo. Committed on 15/12/2025 at 10:16. Pushed by davidedmundson into branch 'master'. ksystemclipboard: Dispatch read events in another thread WaylandClipboard wraps ext_data_control if an application tried to read the clipboard using QClipboard whilst it owns the data control we would deadlock. This was previously being solved by trying to transfer mimedata to the regular clipboard upon gaining focus. However this never worked reliably and efforts to fix this only made it more complicated. To solve the original deadlock all ext_data_control classes now live on another thread which dispatches events on a separate queue. A recursive mutex allows the main thread to read mimedata and no wayland events which change the mimedata process until this is complete.

It seems like i face this only in my main account and only clear desktop screenshot gives me blank element in clipboard new account almost everything seems to be fine
There may be an old value in either the clipboard or Spectacle configuration files that's interfering. Try backing up and then removing these two files in your regular user account $HOME/.config/spectaclerc $HOME/.config/klipperrc Then, log out and back in. Do you still experience the bug after removing those files?
Same behaviour here. I take the screenshot, I paste with ctrl+v, nothing happens, I check my clipboard history (in CopyQ) and I see the screenshot, if I paste from CopyQ, it pastes as expected, and subsequent normal pastes (eg pressing ctrl+v) will paste the screenshot as expected. Still seems like something empties the clipboard after storing the screenshot there.
Reopening, since the bug is still happening with Frameworks 6.22
Setting back to confirmed
