Description
I'm on Ubuntu 22.04 with the latest 5.15 kernel. Running the keybase gui without kbfs (via the command-line flag or the environment variable) causes the client to spin and constantly use at least 33% of a core on my modern CPU. Running with kbfs doesn't; keybase idles at reasonable levels.

Research direction
Start by reproducing the issue with the Keybase GUI on Ubuntu 22.04 using the command-line flag or environment variable that disables KBFS, then compare CPU usage with KBFS enabled. Trace the GUI's no-KBFS startup path and identify the repeated work causing the spin; done means the client idles at reasonable CPU usage without KBFS while retaining normal GUI behavior.
