<![CDATA[Painting artifacts of QGraphicsProxyWidget with QPlainTextEdit]]>Hello, everyone.

There was a problem of repainting the graphical scene when using elements with a QGraphicsProxyWidget with QPlainTextEdit.

It looks like this, as shown in the pictures:


The artifact is observed for Qt version 5.9.1 in Windows and Linux. The minimal compiled example is posted on github: https://github.com/kai66673/TestSceneFail

Any ideas how to avoid such behavior?
