Hi,
I have noticed that the cursor after some time behaves very “sluggish” or “jumpy” in f40 in wayland. I have it on both my laptop and home pc (both run f40, one of them has integrated intel videocard and another one radeon dedicated videocard).
If i switch to x11, the issue is not there.
I have found some older reports on the Internet about it, but most of them were either closed or abandoned .
I recorded a short video to demonstrate it:
Provide some system details
Kernel version which cpu gpu you have.
Can you provide the output of both

I wonder if it is another case of this problem:
Are there multiple device nodes under /dev/input that are receiving your pointer events? I only have one and my mouse is working fine (on Fedora Linux 40 using Sway).
FWIW, Here is a little script that I put together to automate finding what event devices are receiving pointer events (the “script” is the one-liner command that starts with for ...). You have to run it as root and you need to move your mouse continuously while the for loop iterates over your event device nodes.

In the above example, only /dev/input/event6 showed that it was receiving events as I was moving my mouse pointer.
This might not be worth asking, but I’ve had this problem a couple of times to find that I had put something on my laptop’s trackpad (phone, sticker, paper, etc.) while I was using an external mouse, so it was also getting occasional input from the thing on the trackpad.
