Ubuntu 22.04 LST problem

[meineko3]

Recently I upgraded OS from Ubuntu 20.04 LST to 22.04 LST
After the upgrade, I have a problem running phoebe 2.4.4.

For example, phoebe might work well, but the graph did not appear in the following test script.

import phoebe
b=phoebe.default_binary()
b.add_dataset('lc', times=phoebe.linspace(0,2,101))
b.run_compute()
b.plot(x='phases', show=True)

The error message was as follows;

Traceback (most recent call last):
File "/home/meineko/test.py", line 5, in

toolbar_size = self.toolbar.size_request()
AttributeError: 'NavigationToolbar2GTK4' object has no attribute 'size_request'. Did you mean: 'get_size_request'?

What's wrong?
Phoebe worked well in Ubuntu 20.04 LST
Any advice? I appreciate it.

Can you check your version of matplotlib (import matplotlib, print(matplotlib.__version__)? We've had some reports of issues with 3.5.2, although nothing that caused the default options to fail. If that is the culprit, downgrading to 3.5.1 should fix all the plotting issues, and I'll file and issue with all the various compatibility problems and try to bump that up on the priority list.

Thanks!

Thank you, Kyle

Version of matplotlib is 3.6.0

Ok, please downgrade your matplotlib (or perhaps try switching the backend to something other than GTK) and let me know if that does or doesn't fix the issue. I filed an issue to try to support newer version of matplotlib as #636.

Thank you

I downgrade matplotlib from 3.6.0 to 3.5.0.
I can show the graph in phoebe.
