FIX: paintEvent

[GuillaumeFavelier]

Locally I was able to reproduce #8757 (comment) and this small fix did the trick for me. Let's see how it is on Circle.

It works in here too:

I think it's worth restarting the CIs, even though processEvents() is not called directly, I don't want to introduce regressions.

This will only happen if we call setup_time_viewer, which only happens if time_viewer=True (effectively) is used, right? This suggests that if time_viewer=False then the bug will still be there. It seems like we Probably need an equivalent change in very similar code in _pyvista.py, or some other fix, or maybe this belongs at the Brain level?

[GuillaumeFavelier]

You're totally right. And this code in Brain can be removed since self.show() calls self._renderer.show(). I'll update on _pyvista

[GuillaumeFavelier]

... and cannot be removed since ensure_minimum_size has a different version for Brain.

[GuillaumeFavelier]

This is ready on my end.

Thanks @GuillaumeFavelier
