Mac: app GUI freezes when synchronizing with network #25362

   When app is synchronising with network, often app becomes not responsive: Its window is not focused when you press the app icon and it doesn’t handle mouse clicks, always showing loader instead of mouse arrow.

   It still has some progress loading blocks though. After some time while being focused using F3 button on Mac, it may become responsive.

   Expected behavior

   It should always be responsive.

   Actual behavior

   It is not responsive.

   To reproduce

   Just start synchronizing, probably reproduced better on the last percents.

   System information

   Bitocoin Core 23.0 MacBook Air (M1, 2020) Mac 12.4

   The qt widgets gui has a problem with locks, especially when doing computationally expensive tasks like syncing. This has been an ongoing issue for a while. This is being worked on as part of the qml-gui project.

   Additionally, gui related issues should be opened here: https://github.com/bitcoin-core/gui
