Hello,
thanks for your answer.
Yes, it's recommendable because we always build and generate the wheels
with the same numbers.
For bug releases it usually doesn't matter,
but maybe there was a fixed bug that somehow changes the behaviour,
in that case I prefer to always use it.
From the error message I can see it's related to the PYI generation,
so it would be better for you to file a bug report.
The error
BUILDSTDERR: ImportError: /lib64/libQt5MultimediaWidgets.so.5: symbol
_ZN15QHighDpiScaling6factorEPK7QWindow version Qt_5.12.4_PRIVATE_API not
defined in file libQt5Gui.so.5 with link time reference
is the most important bit,
I wonder if somehow that symbol could be related
to a flag that enables High DPI,
or if we could just bypass that warning.
Maybe we could somehow set Qt::AA_EnableHighDpiScaling before that
module gets imported.
Cheers
