As per title. From the flamegraph it looks like this is something to do with display input/output handling.
Waybar locks up and seems to only show the bar on the title screen. It also seems to peg half a core and causes Niri itself to peg a full core. I see no log output.
Here's a flamegraph profile. I see a lot of calls to the display output handling.
Attached is the perf.data, if it helps.

If it helps:
$ waybar --version
Waybar v0.13.0
$ niri --version
niri 25.11
$ cat /etc/os-release
