Bug ID: 489957
Summary: noisy kwin logs from ei and inputcapture subsystems
Classification: Plasma
Product: kwin
Version: 6.1.2
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: gardenofglas...@gmail.com
Target Milestone: ---
SUMMARY
Using input-leap with libei on plasma 6.1 leads to noisy debug logs from kwin
libeis and inputcapture subsystems whenever any input is sent to a client
machine. This is captured by the user journal and leads to lot of spam in the
journal of both server and client machines
STEPS TO REPRODUCE
1. Install libportal from HEAD
2. Build input-leap from HEAD with -DQT_DEFAULT_MAJOR_VERSION=6
-DINPUTLEAP_BUILD_LIBEI=ON
3. Configure two machines as server and client with kde plasma 6.1
4. Run journalctl -f on client and server to tail the logs
5. Activate input-leap and move cursor from server to client. Try some input on
the client using mouse/keyboard
OBSERVED RESULT
kwin logs spammed in journal from inputcapture subsystem on the server for
every input sent to client

EXPECTED RESULT
Debug logs should be gated behind a verbosity/debug kwin flag/environment and
not spam the journal under regular operation
