Bug ID: 513920
Summary: konsole creates unmapped windows
Classification: Applications
Product: konsole
Version First 25.12.0
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: single-process
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
At some point I noticed that `qdbus org.kde.konsole` showed more /Windows/*
than that I had open.
After some investigation it turned out that those windows where unmapped
top-level windows, known to X11 but not visible to or managed by the window
manager.
STEPS TO REPRODUCE
1. Configure konsole to be in single process mode.
2. Run the following a script (perhaps a few times might be needed):
```
#!/usr/bin/env bash
set -euo pipefail
# How many konsole instances to start simultaneously.
INSTANCES=5
# Base temp file prefix.
TMPBASE=$(mktemp -d /tmp/konsole-tabs.XXXXXX)
cleanup()
{
rm -rf "$TMPBASE"
}
trap cleanup EXIT
# Create tab definition files.
for ((i = 0; i < INSTANCES; ++i)); do
cat >"$TMPBASE/tabs-$i" <<EOF
workdir: /bin ;; profile: Profile 1
workdir: /usr ;; profile: Profile 2
EOF
done
for ((i = 0; i < INSTANCES; ++i)); do
setsid konsole --tabs-from-file "$TMPBASE/tabs-$i" -e true </dev/null
>/dev/null 2>&1 &
done
```
Make sure the profiles actually exist (I used two different profiles).
OBSERVED RESULT
All five windows show with:
```
qdbus org.kde.konsole | grep -E '^/Windows/[0-9]+$'
```
but not all five are managed/mapped:
```
wmctrl -lx | grep 'konsole\.konsole'
```
shows less than five (if not then try again, it might be a race condition that
requires a few attempts).
EXPECTED RESULT
All started windows are mapped and visible with `wmctrl -l`.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: none (I use fluxbox as WM)
KDE Frameworks Version: 6.21.0
Qt Version: 6.10.1
ADDITIONAL INFORMATION
Using `setsid konsole --tabs-from-file "$TMPBASE/tabs-$i" -e true </dev/null
>/dev/null 2>&1 &` is to run konsole as "unmanaged", aka without a controlling
tty, in order to have all windows be managed by a single process.
