[BUG]: "Cached on your computer" doesn't update until program restart

[lurch]

What happened?

1. Use Raspberry Pi Imager to write "Raspberry Pi OS (64-bit)" to an SD card
2. Quit and then open Imager again
3. Click on "CHOOSE OS" and "Raspberry Pi OS (64-bit)" is correctly shown as "Cached on your computer"
4. Select "Raspberry Pi OS (32-bit)" and write it to the same SD card
5. Click on "CHOOSE OS" and "Raspberry Pi OS (64-bit)" is still (incorrectly) shown as "Cached on your computer" 🤦
6. Quit and then open Imager again
7. Click on "CHOOSE OS" and "Raspberry Pi OS (32-bit)" is now correctly shown as "Cached on your computer"

(Additional info: I'm running Imager on a Pi5 booted from a USB3 SSD, and I'm using the Pi's microSD slot as my card-writer)

I think I can see what's going on here. We're caching the caching indicator.

As part of reducing the number of network fetches, we also avoid rebuilding the OS list unless we've made a fetch - or changed the device filter.

In this case, I reckon you probably selected 'No filtering' or 'Raspberry Pi 5', and then performed the test - in which case this is certainly errant behaviour - but also expected in the current code.

The obvious minimal-risk step is to get the OS list to rebuild after a download has completed.

Yeah I thought that might be the case 😆

Yes, I was using "No filtering".
