Description
The QtCreator regularly crashes on MacOS (BigSur 11.1).
I haven't yet found a way to reproduce the crash in a fast way, but the crash occurs reliably every day after long computer hibernation.
The setup:
- MacBook with an external display
- External display has QtCreator running
- Lock the computer and turn off the external display
- Wait for x hours (the evening/night in my case)
- Unlock / turn the computer and display back on
With those steps, the QtCreator still running on the external display, the context-menu location (right-click of the mouse) will be all over the place. When the QtCreator is in this state, if I hover the mouse over some code as in to invoke a tooltip, the QtCreator will crash. Otherwise the QtCreator kind of works as normal, but once you invoke a tooltip, a crash happens.
I know it is difficult to debug this before we can find a way to reproduce this faster than waiting x hours. I am happy to help and I am keeping my eye open for this crash.
I've logged the most recent segmentation faults in the past days, and it seems in most cases the crash is in QScreen::availableGeometry(). Seems as if the "d->" would be gone or something.
