You need Qwt 6.2 for Qt6. https://sourceforge.net/p/qwt/git/ci/qwt-6.2
adds all bug fixes that have been made since then, but are not yet
released. ( Note that development happens in a different branch )

Qwt works around known Qt bugs if possible and you find a lot of #ifdefs
in the code to handle issues of specific Qt versions.

Unfortunately I do not have one a workaround for the Qt 6.4 problem when
inserting an QOpenGLWidget into a visible window. But as the majority of
the users does not need the OpenGL path, that might be no problem for you.

In case you are looking for a stable Qt version I would always go with
the latest LTS version, what is Qt 6.2 at the moment. However I'm not
aware of specific bugs that affect Qwt in more recent versions - beside
the one above.

HTH,
