I was playing with thepath editor example and found that with QtAgg if I resize the window I get

QWidget::repaint: Recursive repaint detectedQWidget::paintEngine: Should no longer be calledQPainter::begin: Paint device returned engine == 0, type: 1QPainter::end: Painter not active, abortedSegmentation fault (core dumped)

Removing the blit line from draw as proposed at#11431 fixes this for me. TkAgg works fine whether the blit line is there or not.

I am on Ubuntu 22.04 and tested this withmain.
