Created attachment 165621 [details] 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.
I also can't reproduce this on a clean boot, but I have seen it a few times before the past week or so. Just can't figure out what triggers it.
I can't reproduce it right now, FWIW.
Yes, it seems tricky to reproduce, I'm keeping journalctl -f open while I use my computer to see if I can catch it. If it doesn't happen again for a while I'll just close this as a fluke, if that's preferable.
Had this on my last boot as well. Will try to investigate more if I end up seeing it again as I don't know what triggers it either, unfortunately. That last boot has been on for a while though and the system has been in sleep mode as well. "Feb 06 10:58:33 HOSTNAME kwin_wayland[1383]: QObject::startTimer: Timers cannot have negative intervals" gets reported hundreds of times per second arch, plasma 6 rc2, 3700x+5700xt
We are unsure which timer this is. Can you confirm if any other 3rd party scripts are running? We had a check for all ours but nothing was obvious. If you can put a breakpoint on that line in qtimer.cpp from another computer that would be best.
Hi thecookie, thanks for confirming it's not just me. I'll happily try to help and do what you requested David, but I'm not a developer, just a user, so it might take a bit of time to get that figured out 😁 I'll be looking up info on how to use breakpoints later, I also asked for help with it in the KDE Bugs Matrix room.
