Qt Designer - Print screen of QMainWindow (preview mode) which has QScrollArea

Question

As the title says i want to make some images in QtDesigner.

I used QMainWindow with QMenu, QToolBar, QScrollArea and QStatusBar.

I want the quality to be as best as possible.

OS: Ubuntu 22.04

Fault Print screen attached:

The problem is with the QScrollArea.

Edit: There is no problem if i use pyuic5 command first to compile the .ui files to .py files
