Panel auto-hide pegs CPU

[cargodog]

Overview

I have my panel set to auto-hide, but auto-hide only works in certain applications. When it doesn't work, it stays visible and pegs the CPU.

Expected behavior

When I mouse away from the panel, it should hide itself after some time.

Actual behavior

This only works in some applications. The behavior is reproducible/repeatable.

When it doesn't work:

When I open other apps, such as Brave browser, the panel does not hide and CPU usage increases significantly (cosmic-comp at > 50% CPU).

When it works:

When I open some applications, such as the terminal application (cosmic-term), the panel hides correctly every time and CPU usage is nominal.

Once the panel is hidden, I can switch to a workspace that has Brave browser open and begin using Brave. In this case the panel stays hidden and CPU usage stays nominal. I mention this as evidence that Brave itself is not the cause of CPU utilization. I'm pretty confident it is the cosmic compositor.
