I could only reproduce it twice in a couple of days. The applications open at the time are usually Atom, Firefox, Hexchat, GNOME Files and occasionally Eye of GNOME. I checked resource consumption at the time of the stutters. Memory consumption was about 50% of 8GB, while the swap partition was nearly full (after a long gaming session). Storage device is a SATA SSD. During the stutters and freezes, CPU usage is normal. Through the process list of System Monitor I cannot see any application overusing resources. Temperatures are also normal. One potentially problematic hardware device is the GPU: AMD RX 560 4GB (open source AMDGPU). Its temperature and fan speed were also normal at the time. I know my system is capable of handling this workload. Also, this is only reproducible on Ubuntu 19.10 Eoan with GNOME. The LTS version of Ubuntu (18.04.3) is unaffected. I have used it for months before switching to the latest non-LTS version. What I've tried to stop the freezes: - Closed all running applications and waited. It didn't improve the situation, so I restarted my user session. The freezes continued, so I performed a system reboot, which finally helped normalize things. I did not try to reproduce this on the Wayland session.
