when do you see the lags? usually they're caused by the compositor not rendering fast enough but sometimes they're a hw issue too

Did you see the same lags in X? Can you see the lags when you record the device with evemu-record?

evemu-record output
Comment 3 Nuno Dias 2016-11-14 12:12:15 UTC 
I see the lags everytime, the only thing I need to do is moving the mouse, I only see the lags in the mouse everything else works fine.

If I use X everything works fine, no lag and I don't need to change the speed of the mouse.

If I run evemu-record the mouse is lagging, I attach the output of the evemu-record.

do you mean you're using Wayland when it lags? what input driver are you using when in X? run xinput list to get the mouse's device name and then xinput list-props. if prefixed with "libinput" then it's libinput, otherwise it could be evdev.

the recording doesn't show anything obvious so it's not a hardware problem. Do you have another mouse to test? does it show the same issue?

Sorry about this, the culprit is the mouse
