While dragging individual tracks works, dragging multiple tracks does not. No drag image appears and subsequent drags, even of individual tracks no longer work. The log also reports the following warning in the last case:

warning [Main] QDragManager::drag in possibly invalid state

From binary searching over the snapshot history I could identify

4327e3f35e (Merge pull request #⁠4225 from daschuer/vcpkg_osx)

as the first revision on the main branch that introduces this regression. I have attached a log file from Mixxx from a demo of the issue.

Version: mixxx-2.4-alpha-1181-g9acd6186a5
OS: macOS 12.4 ARM

(I am running the x86 build under Rosetta 2 emulation, I could reproduce the issue on an Intel Mac too, however)

Seems to be addressed in mixxxdj/vcpkg#46

I think we can close this since mixxxdj/vcpkg#46 is merged? @daschuer
