WaveLab 13.0.20 Crash on macOS 15.7.7 - UI Layout Segmentation Fault (Thread 0)

Hi Philippe and WaveLab Team,

I experienced a sudden crash with WaveLab 13 (v13.0.20.1278) on macOS 15.7.7 (Apple Silicon). The application closed unexpectedly during a mouse movement while some plugins were open.

According to the crash log, the crash occurred in the main thread (Thread 0) due to a segmentation fault (EXC_BAD_ACCESS / SIGSEGV) within the Qt layout system, specifically during a UI visibility trigger.

Key lines from the crash log:

  • Exception Type: EXC_BAD_ACCESS (SIGSEGV)
  • Crashed Thread: 0 Dispatch queue: com.apple.main-thread
  • Call Stack:
    0 QtWidgets_WL 0x10a9858cc WL::QLayout::activateRecursiveHelper(WL::QLayoutItem*) + 20
    1 QtWidgets_WL 0x10a985908 WL::QLayout::activateRecursiveHelper(WL::QLayoutItem*) + 80
    2 QtWidgets_WL 0x10a944744 WL::QLayout::activate() + 88
    3 QtWidgets_WL 0x10a9a6c4c WL::QWidgetPrivate::setVisible(bool) + 1128
    18 QtGui_WL 0x109deb98c WL::QGuiApplicationPrivate::processMouseEvent(...)

It seems like a UI rendering conflict in the updated WaveLab 13 graphics framework. Thanks for looking into this!

Best regards,
Jay

What did you do when this happened?

I then restarted Wavelab and attached the report here.
