KDE Neon 5.13 1. Press PrtScr to open Spectacle 2. Check the 'Quit after Save or Copy' checkbox. 3. Click 'Take a New Screenshot'. 4. After taking the screenshot, click 'Copy to Clipboard'. Spectacle will exit. 5. Attempt to paste into GIMP/Telegram/etc. Expected: The taken screenshot was added to the clipboard and can be pasted. Actual: There is no image data on the clipboard.
