With the new signing UX, after I have clicked on the "finish signing" button, Okular becomes unresponsive for a few seconds. During that time, the entire Okular window fades to grey and the window title says "Okular reagiert nicht (Okular doesn't react)". I guess that this is simply the time it takes Okular to do the actual signing. A better progress indicator would be appreciated, but the real problem is that Okular doesn't come back properly. After a few seconds, the new signature appears together with the "this document is digitally signed" message. However, the window remains grey, and the "doesn't react" message does not go away. Only after I switch the focus to another window and then back Okular does everything go back to normal.

It seems like https://gitlab.freedesktop.org/poppler/poppler/-/merge_requests/1611 fixes this.

I can see how that would improve the saving performance. > However, the window remains grey, and the "doesn't react" message does not go away. Only after I switch the focus to another window and then back Okular does everything go back to normal. That's likely a KWin problem, I have observed that with other apps too. I can't reproduce it by sending SIGSTOP/SIGCONT to Okular though, then it un-grays fine
