Because QtVsPlayer use Qmediaplayer :

"Answers 1 : of QWidget::paintEngine: Should no longer be called appears when using QMediaPlayer
Yes, this is a Qt bug. anycodings_qt QWidget::paintEngine is for Qt core anycodings_qt internal use only but QMediaPlayer seems anycodings_qt to be using it, possibly indirectly via anycodings_qt a WA_PaintOnScreen flag being set at anycodings_qt some point inside the library.

For what it's worth, you are not the anycodings_qt only person to notice this issue, and if anycodings_qt the player works the warning can be anycodings_qt ignored fairly safely. Future Qt anycodings_qt updates will likely resolve this issue anycodings_qt over time."
