When I take a screenshot, spectacle occasionally crashes kwin_x11, and I have to restart it from a terminal. In the terminal, I can see the following output after such a crash: QXcbConnection: XCB error: 3 (BadWindow), sequence: 5313, resource id: 52428804, major code: 18 (ChangeProperty), minor code: 0 QXcbConnection: XCB error: 3 (BadWindow), sequence: 20900, resource id: 65011717, major code: 18 (ChangeProperty), minor code: 0 The X11 connection broke: Maximum allowed requested length exceeded (code 4) XIO: fatal IO error 2 (Datei oder Verzeichnis nicht gefunden) on X server ":0" after 421661 requests (421661 known processed) with 0 events remaining.

It would be helpful if you could test again with a recent version and indicate what settings you are using in Spectacle (and possibly your graphics driver).
Thanks for the reply. I've just tested with spectacle 17.12.1, and everything seems to be working fine now.
Thanks for testing. It's always nice to have one less bug with "crash" in the title ;)
