SUMMARY If I have evolution (mail client) opened and switch TTY to something without an X session and then back, evolution will then display an error message. Although evolution is not a KDE application, I think this might have to do with KDE software, since (a) X-related things are handled by kwin, (b) a similar issue occurs when logging out of a plasma session and then logging in again (https://bugs.kde.org/show_bug.cgi?id=433293). STEPS TO REPRODUCE 1. Launch evolution (mail client). 2. With the evolution window still opened, switch TTYs through e.g. Ctrl + Alt + F2 (or some other F<number>). 3. Switch back to the TTY that has the X session with evolution. OBSERVED RESULT Oftentimes, evolution will show a warning about streaming operation being unable to complete, which stays there until the application is closed and launched again. EXPECTED RESULT Nothing special should happen. SOFTWARE/OS VERSIONS Operating System: Debian GNU/Linux KDE Plasma Version: 5.24.3 KDE Frameworks Version: 5.90.0 Qt Version: 5.15.2 Kernel Version: 5.16.0-5-amd64 (64-bit) Graphics Platform: X11 Processors: 16 × AMD Ryzen 7 2700 Eight-Core Processor Memory: 15.6 GiB of RAM Graphics Processor: AMD VEGA10
Created attachment 147806 [details] evolution_warning Attached is a screenshot of the warning.
Evolution isn't a KDE app, and the TTY switching system isn't in KDE code either. This isn't an issue in any KDE software, so I would encourage yo to report it to the Evolution developers.
