My system is super slow and choppy (randomly, sometimes its fine) and this happens when kwin_x11 is stuck between 5 and 15% CPU load. They are for sure connected. When my system is normal kwin_x11 is no where to be seen (very low CPU load).
Even after a reboot or shutdown it stays the same. I have to reboot 100 times before it decides to act normal. The system is not usable like this.
I’m running on the System76 Galago Pro with the i7-7500u Intel CPU/GPU. I switch between the laptop screen at 1080P and my 42" 4K screen. The issue is much improved when at 1080P but is still an issue.
Someone please help!
