I am using QT 5.11.1 and written a wrapper for GUI part of my application in QT.
All the Functionalities like Pan, zoom In, zoom out etc works fine albeit a little slow.
I have heard that In QT 5.11.1 native rendering can be enabled by Environment variable
QT_XCB_NATIVE_PAINTING. So when i use this environment all the Functionalities like Pan, zoom In, zoom out etc becomes fast, but some portion of the application is not rendered.
I have attached screenshot of my application in which the area in black is not rendered.!
Thanks in advance.

I think this is a bug in QPainter::drawPixmap that places the offscreen QPixmap onto the wrong location. The black area is pretty much the same height as the sum of the height of the menubar + toolbar. I assume a problem in
Seems already reported
