kwin_x11 and xorg log
SUMMARY
The fps will drop to 30 in 2-4hours, and drop to 20fps in 4 - 8hours, and will
keep decline.
In this situaltion, Xorg will take about 50% cpu even close all windows(cpu
consume will drop a little bit, but it will back to 50% if there are any action
performed), and will take more with the time passing. eg: It will take about
100% when fps go down to 15-20.
kwin_x11 consume up to 20% cpu according the number of windows.
Also tested glxgears, and it shows good performance with 60 fps.
Tried restart plasmashell with "--replace" option, not work. The only solution
i found is to restart kwin_11 with "--replace" options. But it will keep
happened in next 2hours.
There are no related error log print by Xorg or Kwin_x11, i will attach logs
below.
STEPS TO REPRODUCE
1. Login to system
2. Normal use
3. FPS drop
