SUMMARY I have experience multiple instances of mouse/keyboard going fully unresponsive after accepting the input capture portal prompt. I cannot reproduce it at will but it occurs with inputleap on a kde plasma wayland 6.1.4 system using git master libportal on occasion. STEPS TO REPRODUCE 1. use a software such as inputleap to capture input 2. start the software and accept the inputcapture portal 3. occasionally all input devices go unresponsive SOFTWARE/OS VERSIONS Linux/KDE Plasma: Ubuntu Noble Neon KDE Plasma Version: 6.1.4 KDE Frameworks Version: 6.5.0 Qt Version: 6.7.2 ADDITIONAL INFORMATION Originally reported and partially diagnosed as a possible kwin issue on https://github.com/flatpak/libportal/issues/152#issuecomment-2323566346 Sep 01 14:29:02 garrett-desktop systemd[2303]: Started app-\x2fhome\x2fgarrett\x2finput\x2dleap\x2dubuntu\x2d22\x2d04\x2fbin\x2finput\x2dleap@c9345465f7bc42708df765f5fff41d9b.service - /home/garrett/input-leap-ubuntu-22-04/bin/input-leap.

Git commit 88a92f9ebbfe542f47d0fe3c99ac2f1c46281f5b by David Redondo. Committed on 04/12/2024 at 17:14. Pushed by davidre into branch 'master'. Remove inputcapture if eis client disconnects Otherwise input can get stuck because the client may base its decision to release the capture on the input event it receives.
