note that i'm using debian sid and xfce4 it shows full of red bars on htop on one of the core between two(i have atom n455 cpu) iirc red bars means kernel threads
i've tested using debian's boot menu so only thing changed is kernel version it was fine on kernel 5.10 it's happening on kernel 5.14 and 5.15 i don't know exactly how to represent, but it isn't hard to if i just do something like browsing or reading pdf it just starts to happen and never stops even after i close all apps or log out https://asciinema.org/a/xTXqyZhg06enfrcHbuhasGJrm https://asciinema.org/a/y0klCFDWSOsjjAQTUHlHM84mq 1st link is when it's fine(right after boot) 2nd link is when it happens there is no difference on application running between two xserver is unrelated it's high cpu usage is just because of more updates on htop screen if i watch htop on ctrl+alt+f1 terminal xserver isn't even on the first page but htop still shows high cpu usage https://asciinema.org/a/l81ZO3hSHbA4jLm6fwLlIrfUS recorded on ctrl+alt+f1 terminal ran htop as root and enabled to show kernel threads tho cpu usage of kernel threads aren't being displayed
