Description of problem: On my system, with a AMD Ryzen 3400G, with 8 threads at 1.4 GHz or so at the least, running kernel.org 5.9.1. and Fedora 32 I see messages in the logs like: /usr/libexec/gdm-x-session[3582]: (EE) event3 - LITEON Technology USB Multimedia Keyboard: client bug: event processing lagging behind by 14ms, your system is too slow Version-Release number of selected component (if applicable): gnome-shell-3.36.7-1.fc32.x86_64 How reproducible: Use Fedora 32. Check the logs every now and then, e.g. using `journalctl -b --no-hostname -o short-monotonic`. Actual results: [409963.114696] /usr/libexec/gdm-x-session[3582]: (EE) event3 - LITEON Technology USB Multimedia Keyboard: client bug: event processing lagging behind by 34ms, your system is too slow [409976.538604] /usr/libexec/gdm-x-session[3582]: (EE) event3 - LITEON Technology USB Multimedia Keyboard: client bug: event processing lagging behind by 14ms, your system is too slow Expected results: No such messages. Additional info: Some googling leads me to believe that this is not a system problem but a compositer issue. This means that on this system it means that the compisiter was perhaps not well written and/or perhaps not well enough optimized.

After switching to wayland (the newer, leaner and meaner implementation of some gui stuff) the problem persists. It appears the rootcause is not in xorg nor wayland, or is in both xorg and wayland). When 8 threads and 16 GB of RAM are not enough, what can run this software without these messages?
Same, occurs in xorg and wayland when running graphical intensive app (aka vulcan based game). 3800X, 5700xt, 32GB ram. JournalCTL and xorg log both show the same: [ 365.134] (EE) event9 - Logitech USB Receiver: client bug: event processing lagging behind by 33ms, your system is too slow [ 578.780] (EE) event9 - Logitech USB Receiver: client bug: event processing lagging behind by 18ms, your system is too slow [ 625.305] (EE) event9 - Logitech USB Receiver: client bug: event processing lagging behind by 27ms, your system is too slow [ 668.967] (EE) event9 - Logitech USB Receiver: client bug: event processing lagging behind by 31ms, your system is too slow [ 676.659] (EE) event9 - Logitech USB Receiver: client bug: event processing lagging behind by 27ms, your system is too slow [ 676.659] (EE) event9 - Logitech USB Receiver: WARNING: log rate limit exceeded (5 msgs per 60min).

Fedora 34 'upgrade', same issue.
We migrated from an AMD 3400g to a 5700g and still see the same bogus issue.
Any updates?
Is it possible that gnome-shell's JS garbage collection causes these delays?
Or USB powersave? We do not have a LITEON keybaord but a Logitech 'standard' international keyboard. Where does gnome get this false info from?
I have this same issue Fedora 35 Silverblue on an AMD Ryzen 5 PRO 2400G system with 32G of RAM.

It can be caused by USB autosuspend which is set to only 2 seconds. It should be increased to e.g. 60 seconds or disabled.

This error seems to have stopped with the installation of the 6.0.5 kernel in Fedora 36. It was happening multiple times a day before the update, have not yet seen it in November.
I am also running kernel 6.0.x for a few weeks on F37 and also don't see those messages anymore, but I've missed the point when the stopped, I'm currently on 6.0.7-301 kernel build
