I am trying to update spyder on rawhide and F35. The main issue I have is that pyqt requirements are strict. From the setup file,
'pyqt5<5.13', 'pyqtwebengine<5.13',
Fedora has 5.15.x. If I relax QT versions, built and launch spyder, I get this error and spyder fails to launch.

Do you know where is this error triggered? Try explicitly converting the floats to integers.
Yeah, that sounds more like a common Python 3.10 issue than an issue with newer PyQt.
No, this is definitely a change in PyQt, or at least sip, cf. https://github.com/matplotlib/matplotlib/pull/17565 https://github.com/matplotlib/matplotlib/pull/17600
The fix is 'easy', but you need to find everywhere that might trigger it. QSize takes an int now, as it does in Qt (from C++), instead of coercing a float.
Python 3.10 also contains a change where you can no longer pass floats to extension modules in cases where there would a loss of precision (e.g., as an int).
