Classification: Plasma
Product: kwin
Version: 5.93.0

My kwinrc
SUMMARY
In Plasma 6 RC2, once I start typing or moving my cursor, kwin spams
"QObject::startTimer: Timers cannot have negative intervals" in the systemd
journal. Several of these pop up every second.
If I don't move my mouse or use the keyboard, it stops.
STEPS TO REPRODUCE
1. On a systemd based computer, sign in to a Plasma 6 RC2 session
2. Execute journalctl -f in a terminal
3. Move the mouse or type anywhere while observing the journal
OBSERVED RESULT
Almost hundreds of QObject::startTimer related warnings can pop up each second.
EXPECTED RESULT
Nothing special should be logged during input.
SOFTWARE/OS VERSIONS
Linux kernel: 6.7.4
KDE Plasma Version: 5.93.0
KDE Frameworks Version: 5.249.0
Qt Version: 6.7.0 Beta 2
ADDITIONAL INFORMATION
Tried two different mice just in case.
This does NOT happen on my Lenovo IdeaPad 5 Pro 16ACH6, which is also using
Arch Linux with the same software versions mentioned above.
I have not had time to test in a Neon Unstable environment yet. I will do so
later today.
