Arch Linux

Description:

After upgrade from xorg-server-21.1.2-2 to xorg-server-21.1.3-1 I started noticing periodic (very frequent) freezes in mouse pointer movement. I also noticed some keys being ignored as I typed on the keyboard. Mouse (both touchpad and wireless mouse) and keyboard were affected by the periodic freezes.

I see these errors in /var/log/Xorg.0.log:

ASUE1209:00 is the laptop's touchpad. Logitech M325 is the wireless mouse. Logitech K750 is the wireless keyboard.

I have downgroaded to xorg-server-21.1.2-2 and the freezes go away.

Laptop is ASUS ROG Zephyrus G15 GA503QR with AMD Ryzen 9 5900HS processor.
