When changing window size or using fullscreen when using vulkan with the latest qt from homebrew (6.8.0 and later), the application will freeze when resizing the window and then crash with a blue screen. It throws the error qt.gui.metal Timed out waiting for display lock. Switching to qt 6.7.3 or earlier causes the issue to disappear and things work normally. This is the program used which works with 6.7.3 but breaks with 6.8.1 with no code changes on macOS arm64. broken version:      chiaki-ng-macos_arm64-Release-broken.dmg       vs fixed version:      chiaki-ng-macos_arm64-Release-fixed.dmg      . and the code is available here: https://github.com/streetpea/chiaki-ng
