Dear Claus,
thank you for your answer.
At home, the IDE is only working with gtk since on my manjaro the QT6
is only on 6.11 not yet on 6.12 therefore I don't have those
QTextCursor::setPosition: Position 'X' out of range.
At closing it says : double free or corruption (!prev) and I don't know
how to correct this memory corruption.
Best regards.
