It could be QTBUG-55918. If so, try setting the opacity as described there.
If not, there are a couple other related bugs. I.e., this is not likely to
be a PyQt 5.7 issue, but a Qt 5.7 issue. HTH,
Oliver

Hey
Using it 1st time so apologise for any weird errors in my submission.
In any case I have a QGraphicsView/Scene node editor system. I use
widgets/checkboxes/lineedits/other in my view with QRectItem as a parent.
When I upgraded from 5.4.x to 5.7.1 I can notice some visual glitches. When
I zoom in/out pan around the drawing of widgets gets messed up.
I'm using dockwidget to hold my node editor and other things.
Attached a jpg example of issue.
Is that a bug, or I need to change some settings on Scene/View?
Using:
self.setRenderHint(QPainter.Antialiasing)self.setViewportUpdateMode(QGraphicsView.Smar \
tViewportUpdate)self.setTransformationAnchor(QGraphicsView.AnchorUnderMouse)self.setRe \
sizeAnchor(QGraphicsView.AnchorUnderMouse)self.setDragMode(QGraphicsView.ScrollHandDrag)
Regards
Dariusz
