FIX: paintEvent/resizeEvent & update

[GuillaumeFavelier]

It seems that #8852 was not enough. I'll investigate the issue thoroughly in here and come back to #9010 afterwards.

Progress:

• Fix "minimized" issue
• Fix update issue

ToDo:

• Touch example as baseline
• Revert qt_disable_paint
• Investigate set_3d_view

Related to #9010 (comment), #8828

Also can you check that tutorials/sample-datasets/plot_phantom_4DBTi.py plots correctly in this PR (make some change to it)? On my system the first plot looks like:

And if I click-drag anywhere it gets fixed:

So it seems to just be some update problem here, too.

[GuillaumeFavelier]

I'll add it to the list

[GuillaumeFavelier]

The 'minimized' rendering issue is reproduced:

Can you reproduce locally with PATTERN=source_alignment make html_dev-pattern? That way you won't have to wait for CircleCI (and use up its cycles).

Some hint at the problem is perhaps that the plain plot_alignment calls are bad, but the one that changes the view looks good. So somehow that view-setting call fixes things.

[GuillaumeFavelier]

I tried and I do not reproduce with my usual desktop manager. A similar environment is probably building on a TTY with a running xvfb though.

[GuillaumeFavelier]

qt_disable_paint is definitely related to the issue somehow:

[GuillaumeFavelier]

Apparently fixed with Update&Process :

@GuillaumeFavelier we are also seeing some problems on CircleCI for main:

Traceback (most recent call last):

    rst = scraper(block, block_vars, gallery_conf)

Is this a PyVista bug with their scraper?

[larsoner]

So far these both look good at least!

Is this a PyVista bug with their scraper?

Hm... probably 🤔

[GuillaumeFavelier]

I'm still trying to figure out where this comes from. AFAIK, self.image is a property of BasePlotter, I don't understand why the scraper complains.

[larsoner]

Okay well I'll merge this once CIs come back happy, feel free to open a new PR for that error

[GuillaumeFavelier]

Will do

[larsoner]

Thanks @GuillaumeFavelier !
