KWin main thread hanging repeatedly – RTX 5080 on Wayland
System:
- Bazzite 43.20260313 (Fedora 43)
- KDE Plasma / Wayland
- GPU: NVIDIA GeForce RTX 5080
- Nvidia Driver: 595.45.04
- CPU: AMD Ryzen
- RAM: 31 GiB
- Kernel: 6.17.7-ba28.fc43.x86_64
- System is installed on an SSD (switching to NVMe2 soon)
Problem:
The system freezes repeatedly and unpredictably for short periods. CPU, GPU and RAM are barely under load during the freezes. Sometimes even mouse movement is not possible.
Relevant log output (
Also spotted in the logs:
What I already checked:
- Swap, RAM, temperatures – all fine
- No I/O errors in dmesg
- swappiness already set to 10
Question:
Any ideas what could be the problem or what to look after? I also tried the testing branch, no difference.
