Steps to reproduce

  1. Start Element, using Rust crypto
  2. Leave it idling

Outcome

What did you expect?

The app should not cause my fan to spin while idle.

What happened instead?

Every 20 seconds, my fan spins up and an error is logged in the console: "Backup: Error processing backup request for rust crypto-sdk Error: failed to read or write to the crypto store DomException UnknownError (0): The operation failed for reasons unrelated to the database itself and not covered by any other error code." Presumably these are connected?

Some further information: this only started a few days ago, after my client performed some sort of migration related to crypto keys. The first time the migration happened, I thought my client was frozen so I closed the tab in the middle of the operation (could it be related?). The second time I checked the console to see what was happening, and allowed the migration to complete.

The migration will have been the (first) fix to #26488. Per that issue, it turns out that there is still more work to do.

Closing as a duplicate of #26488. Thanks for the report though!
