Description Nicolas Fella 2022-10-04 19:46:56 UTC

STEPS TO REPRODUCE
1. Install htop 
2. Lauch htop from Kickoff

OBSERVED RESULT
A Konsole window with htop appears, but the bouncing cursor keeps bouncing for a while until it eventually times out

EXPECTED RESULT
The bouncing cursor stops as soon as the terminal window is there

SOFTWARE/OS VERSIONS
KDE Plasma Version: master (5.25.90)
KDE Frameworks Version: master
Qt Version: 5.15.6-kde

ADDITIONAL INFORMATION

The problem is generic to all apps with Terminal=true

We launch a particular desktop file e.g. htop.desktop, and then wait for a window matching that desktop file to appear, but instead a window with org.kde.konsole for its app_id appears, so we never terminate the startup feedback until some timeout

Comment 1 Nicolas Fella 2022-10-04 19:50:41 UTC

In terms of solutions we could

1. Patch htop et al to have StartupNotify=false
2. Force StartupNotify=false for all terminal apps in KIO::ApplicationLauncherJob
3. Force StartupNotify=false for all terminal apps in KWin

Not great solutions since we would lose the bouncing cursor completely

4. Special-case inside kwin that when we know a terminal app is launched we "wait" for Konsole/the default terminal app instead

4 seems nice.
