Keybase slowdown gnome and break my GUI

I've found an issue where Keybase has been heating up my computer and breaking my GUI.

My information:

- **ubuntu**: Linux 5.8.0-48-generic #54~20.04.1-Ubuntu
- **gnome-shell**: 3.36.7-0ubuntu0.20.04.1
- **nvidia-driver-418-server**: 418.181.07-0ubuntu0.20.04.1


dmesg:

```

Start by reproducing the slowdown and GUI failures on the listed Ubuntu, Linux, GNOME, and NVIDIA versions, then compare the dmesg and journalctl output with Keybase activity. Done means identifying whether Keybase triggers the reported segfaults and providing a verified fix or compatibility resolution.
