Errors that I get running fsleyes

I could fix this by downgrading to matplotlib 3.4.3, which is the stable version. Fedora 35 has 3.5.0rc1.

I also changed line 305 of `/usr/lib64/python3.10/site-packages/wx/lib/stattext.py` to `x = (width - w)//2` and now it seems like fsleyes works again.

Thanks for the bug report. Are you on X11 or Wayland? I think we're still waiting for a wxpython update for Wayland:

https://github.com/pauldmccarthy/fsleyes/issues/22


Generally, this looks like two issues. I'll file the first with fsleyes upstream now, and then we'll file another one for wxpython

I get this when I run it:

```
TypeError: DC.DrawText(): arguments did not match any overloaded call:
  overload 1: argument 2 has unexpected type 'float'         
  overload 2: argument 2 has unexpected type 'float'                                                                                    
Traceback (most recent call last): 
  File "/usr/lib64/python3.10/site-packages/wx/lib/stattext.py", line 306, in OnPaint
    dc.DrawText(line, x, y)            
```

Cheers,

Would you have a test file that we could submit to upstream to reproduce the error by any chance?

I have tried it both on X11 and Wayland with the same results. I'm not sure what test file to submit, because I couldn't open any Nifti files whatsoever. For example, one of the FSL templates. But I've fixed this problem by downgrading matplotlib to 3.4.3, which is the stable version, because Fedora 35 has 3.5.0rc1 and the fsleyes script parses the version number incorrectly (it tries to convert "0rc1" into a number and fails. Second, I've fixed the error you mentioned by changing wxPython's code as I mentioned above on comment 3 (and BTW I submitted a pull request with this change to wxPython's Github repo). I did NOT get the same error as the Github issue you mentioned. By doing these two things that I mentioned, I could now open Nifti files on Wayland and got no errors on the terminal, but the interface didn't look totally right to me. For the moment, I've installed fsleyes on miniconda, just to be sure.

FEDORA-2022-abf5c05534 has been submitted as an update to Fedora 35. https://bodhi.fedoraproject.org/updates/FEDORA-2022-abf5c05534

Could you try the update please? It seems to work fine here now for me here on Wayland (I tested with the nifti images in the fsleyes sources).

Matplotlib has now been updated to 3.5.1 in Fedora 35 too, so you should stop seeing the warnings/errors on your terminal also.

These are the package versions I have:

It works fine, thank you.
