wxPython 4.1.1 or newer required for displaycal 3.9.3-1
standard functionality to work properly.
Current wxPython version is incompatible.

Additional info:
* package version(s)
displaycal 3.9.3-1
python-wxpython 1:
* config and/or log files etc.
* link to upstream bug report, if any

Steps to reproduce:
If you open displaycal and delete one profile you get an unresolvable error:
_ScrolledWindowBase.Scroll(): arguments did not match any overloaded call:
WARNING: Your version of wxPython (4.0.7.post2) is outdated and no longer supported.
You should consider updating to wxPython 4.1.1 or newer.

python-wxpython 4.1.1-1 was epoch downgraded due to  FS#70908 . Is that still an issue?

@Rukula if you build python-wxpython 4.1.1 [1] does that solve both the version warning and the error?

@loqs It fixed the version warning but not the error. I have now python-wxpython 4.1.1-1 and wxgtk-common installed. I managed to recreate a similar error by opening displaycal, clicking on "?" and then "about" and clicking, scrolling and dragging the windows some time until it seemingly randomly appears. See screenshot Error 2.

Filed a pull request on the displaycal repo, which should fix the bug. WXPython has already fixed the bug in their recent code too, it should come around as a release soon.

According to the latest wxpython release 4.1.1 (25 Nov, 2020) supports only up to python 3.9:
The fix on the wxpython side for my specific bug with displaycals use of wxpython was made on Dec 1, 2021 ( ), which there is no official wxpython release for yet. This problem can only fully be fixed, once there is a wxpython release which supports python 3.10.
