Hey,
Using raspberry pi 4 with ARCH and XFCE.
I was getting some severe pointer lag after the last update. After some investigation i've discovered the following:
-I've tried a couple of different mice and both lag. One was a Kingston Bluetooth mouse and the other was XP-Pen tablet.
-I've changed usbhid.mousepoll to 8 and 16, the behavior changes but doesn't improve.
-My processor says it's working at 1.0MHz, so, not getting throttled I guess.
-Every event pauses until the mouse pointer is fully updated, which means every program stops until the pointer stops moving. I can even disrupt the shutdown process by continuously moving the mouse!
Thanks.
