The crashes happened because somebody was calling processEvents() from a mouse/touch event handler that was running for a long time. If we called processEvents() from the onPressed handler, and we released the mouse while still not having returned from the onPressed handler, it meant that we were actually delivering the release event before the press event was fully delivered... This should normally not be a problem, but QQuickWindow is reusing the QQuickPointerEvent object for each incoming QEvent, which meant that when we were delivering the release event, it would reuse (and overwrite) the QQuickPointerEvent that the press event handler is still using.... This then caused some assumptions that the code made to be wrong. This only avoids the crashes, and doesn't really fix the "out-of-order" delivery and the state inconsistency that this can lead to (e.g. mouse button states might be still wrong). But on the other hand, it is not the recommended way of making a long-running handler not block the application. The proper way is to create a thread that will run in the background, so that there would be no need to call processEvents() in the event handler.

If there is an invisible window that will not be rendered but is constantly requested to render, updatePending is always set. This prevented purging of already unneeded textures, and meant endSync() was never called and m_texturesToDelete was never cleared. Added a fix to clear the updatePending flag regardless of visibility. Task-number: QTBUG-66116 Change-Id: Ib8bf453a3dee18d3d43342580c619664b701acae Reviewed-by: Shawn Rutledge <shawn.rutledge@qt.io>

MemberData would get reallocated to exactly the required new size. In case there's one large object dominating things, this would then trigger a GC run on every reallocation, causing a quadratic runtime behaviour due to marking and sweeping that memory.

Qt Quick has a dependency to gui, but there is no way to disable an entire configure module from the configure system.
