It crashes in qwindowsnativeimage.cpp, line 118:
m_image = QImage(bits, width, height, format); Q_ASSERT(m_image.paintEngine()->type() == QPaintEngine::Raster); static_cast<QRasterPaintEngine *>(m_image.paintEngine())->setDC(m_hdc);
.paintEngine() is nullptr because m_image is invalid as QImage() ctor didn't create the image because negative height was passed to it.
QWindowSystemInterface::sendWindowSystemEvents tries to send an event (that was presumably originated from WM_SIZE/WM_MOVE) with incorrect set of data:
- event 0x00000000557394a0
- [QWindowSystemInterfacePrivate::GeometryChangeEvent]
+ QWindowSystemInterfacePrivate::WindowSystemEvent
+ tlw guarded pointer to subclass of QObject of type "QWindow" QPointer<QWindow>
+ newGeometry { x = -31992, y = -31970, width = 144, height = -11 } QRect
+ oldGeometry { x = 0, y = 0, width = 0, height = 0 } QRect
+ __vfptr 0x000007fee29fa100
type GeometryChange (2) QWindowSystemInterfacePrivate::EventType
flags 0 int
eventAccepted true bool
+ flags {i=0 } QFlags<enum QEventLoop::ProcessEventsFlag>
nevents 1 int
The values in newGeometry rectangle are invalid (height is negative).
Happens quite often to different users on a diverse set of environments. Seems like the trigger is waking up from sleep.
Could be related to QTBUG-24189
