How do I diagnose mouse lag/stuttering ?

i3wm
wireless mouse (batteries refreshed and tested with new mouse)

Recently I have been experiencing intermittent but substantial mouse lag/stuttering, primarily while moving the pointer over a web browser.  I have tried several browsers (Firefox, Chromium, qutebrowser, Falkon, Vivaldi, etc) to see if it was specific to one and it is not.  I've opened htop to see if the cpu load increased and it did not.  I've searched the forum and google without luck.  How do I troubleshoot this problem?

Thank you

What graphics card do you use and what drivers?

The most important question is whether this is reproducable w/ a wired mouse (to rule out any issues w/ eg. the BT stack - esp. if you're on a 2.4GHz WiFi connection, the browser might generate traffic and the 2.4GHz range is totally crowded and BT would use the same antenna as the WiFi)

Not to honor the shameless bump on this topic, but Logitech wireless mice have a peculiar issue where plugging the USB dongle directly into a laptop can sometimes cause stutter and similar behavior as if the battery is empty. The (bizarre) fix is to plug the USB dongle in the USB port of a keyboard, or any type of USB hub instead. There is a great non-Arch forum post out there that some Googling will locate, at least a couple of years ago it did. It has something to do with hardware interference when the dongle is plugged directly into the laptop's USB port and I believe it's not related to the O/S.

You may compare differents methods of graphics accelerations and see if that help. When I changed my hardware, I had laggy mouse with UXA in gtk applications. Altough it does not concern mouse problems directly, you can get some benchmarks with gtkperf.
