### Bug description

Sometime, the client needs to produce lots of log because there are lots of changes to sync
In such cases, the logs will significantly slow down the main thread responsible for executing the synchronization and handling user interaction with the user interface

### Steps to reproduce

1. Run the desktop client
2. Produce a significant amount of changes via for example rename of folders with lots of files in them (think about a deep hierarchy of folders with many files > 50 000)
3. the client can be kept busy producing logs for several seconds with visible slow down

### Expected behavior

The client would never block handling of user interaction actions.
