Dear Maintainer, I upgraded today to Bullseye (dist-upgrade, not a new install). I work a lot with PDF files and really enjoyed the possibility of creating shortcuts in Okular, in the previous versions. Now, to this end one creates a new scheme: fine. I did: Settings > Configure keyboard shortcuts > Manage schemes > New Since no shortcut is already present, I try to add one for searching. I click on the "Shortcut" column, line "Find", select Custom on the radio, click on "None", press Ctrl+F. Nothing happens in Okular, but the window manager is impaired. Moving Okular's window makes a copy of the window. Alt+Tab to switch to the terminal below does not switch. My usual Function key shortcuts to switch between virtual screens no longer work. I use Fvwm. I can click in the Pager to switch virtual screens. From there, everything works in the window manager. If I go back to the virtual screen where Okular is, the screen remains black. But the Function keys work again. I tried 4 times, changing twice the function (eg Find) and the key combo. I could only quit Okular with 'kill'. When I try to install the testing version, hoping the bug has been solved, apt wants to upgrade lic6 also, which might lead to trouble down the road on an otherwise stable Debian. So: - can't configure shortcuts because Okular... - crashes when I try and... - takes part of X or fvwm with it. Thanks for your help! Sebastien.
