Several days ago, i upgraded my Kernel to 5.15.2-2. Initially it seemed fine, but after waking up from sleep, my wireless Microsoft mouse was almost unusable. it was very sticky that many many wheeling just made it move a little bit up or down the scrolling bar.
It was just the same issue i encountered before years ago when I was first trying Kernel 5. i didn’t dig too much, but it seems that it was a Kernel bug yet didn’t fixed. Once again i simply downgrade to 4.19.
I recommend go to the testing branch which has fixed kernels. AX210 bluetooth has a issue now and I don’t know if it has been fixed. Go to the testing branch is not so dangerous and bugs can be fixed faster.
