Very large font in some distributions

Distribution

Bug description

In one of the RedHat based distributions I saw incorrect display of national text characters in the programme:

• The characters appear cropped at the top and bottom.
• The font size is very large.
• There is almost no line spacing in the hex editor window (monospaced font).

Steps to reproduce

Expected behavior

Additional information

The following edits had to be made for correction:

IMSProg_programmer/main.cpp

- 21     QFont font("Monospace");
+ 21     QFont font("OpenSans");
- 23     font.setPointSize(12);
+ 23     font.setPointSize(11);

MSProg_programmer/mainwindow.cpp

- 109     heFont = QFont("Monospace", 10);
+ 109     heFont = QFont("DejaVu Sans Mono", 10);

No such problems are observed with the same IMSProg distribution on Fedora 38.

What is the situation with fonts in different distributions?
