High CPU usage on "Manage" screen

[demoth]

Is there an existing issue for this?

• I have searched the existing issues and found none matching what I'm reporting.

Bug Description

On all other tabs the cpu usage is negligible. But when I switch to the Manage screen cpu usage goes to 10% (which is equivalent of 3 cores at 100% on my system) and stays there. Very consistent (tried switching tabs, restarting the app and the system)

Steps to reproduce the behavior

1. Open Snap Store
2. Open system monitor (any)
3. Switch between Manage and any other tab

Expected behavior

The cpu on each tab should stay more or less on the same level.

Ubuntu release

24.04 LTS
