Change Details

Unfortunately Aurorae decoration engine creates several internal clients per each decoration. One of those clients represents QOffscreenSurface, which is not a toplevel. Given that no QWindow object will be found for such clients, m_internalWindowFlags contains undefined value. The client may or may not have frameless window hint, etc. Luckily, QOffscreenSurface sets FramelessWindowHint flag, but because InternalClient is not able to find matching QWindow object, cached QWindow flags won't have that hint set. Thus InternalClient will attempt to decorate QOffscreenSurface. A new Aurorae decoration will be created, which means a new QOffscreenSurface will be created, which means a new Aurorae decoration will be created, and so on. This change restricts subset of internal clients that can be decorated. Only clients with valid m_internalWindow can be decorated. If m_internalWindow isn't null, then m_internalWindowFlags is guaranteed to be valid as well. BUG: 407612 FIXED-IN: 5.16.3
