QGraphicsView picture quality Error.

[Pada_]

I am using Qt5.4 / Linux.

I know I have QGraphicsTextItem in QGraphicsView, but I am using QTextEdit for the proxyWidget of QGraphicsItem for convenience.

The item is normally created in GraphicsView, but is it a quality problem? There are times when the TextEdit Border is not working properly. If you move the position of the item, there are times when there is no other place, and sometimes it is all coming out normally. Or zoom out or disappear. This is not a problem with TextEdit alone. Items using other proxyWidgets are also the same symptom. Can you fix it?

Hi,

Before trying to fix anything, you should build your application using a current version of Qt. 5.4 is really outdated and we are currently at 5.12 with 5.13 around the corner.

@SGaist

Currently only 5.4 or 5.7 are available.

The same phenomenon occurs in 5.7. When enlarged or moved, it is displayed normally on the screen again.

Can you provide a minimal compilable example that shows that behaviour ?
