Problem with wx.aui.AuiManager (wxWidget 3.1.6 --> 3.1.7)

Operating system: Windows 10 wxPython version & source: 4.1.2a1.dev5434+7d45ee6a (whl) Python version & source: 3.10.4

Description of the problem: Each time you drag one floating pane window, the other floating panes drift. In the demo video, every time you drag the pane [p1], the pane [p2] drifts. Once you touch the pane [p2], it will no longer move.

Since 4.1.2a1.dev5426+502d8354 is no problem, this bug seems to be related to the change of wxWidget 3.1.6 --> 3.1.7

Code Example (click to expand)

import sys
import wx
from wx import aui


print("Python {}".format(sys.version))
print("wxPython {}".format(wx.version()))

class Frame(wx.Frame):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)

        self._mgr = aui.AuiManager()
        self._mgr.SetManagedWindow(self)

        self.p0 = wx.Panel(self)
        self.p1 = wx.Panel(self, size=(100,100))
        self.p2 = wx.Panel(self, size=(100,100))

        self._mgr.AddPane(self.p0, aui.AuiPaneInfo().CenterPane())
        self._mgr.AddPane(self.p1, aui.AuiPaneInfo().Float().Caption("p1"))
        self._mgr.AddPane(self.p2, aui.AuiPaneInfo().Float().Caption("p2"))
        self._mgr.Update()

if __name__ == "__main__":
    app = wx.App()
    frm = Frame(None)
    frm.Show()
    app.MainLoop()

I don't see this problem on Linux, so perhaps it affects Windows only? Do you want to report it to wxWidgets? It doesn't seem like something that could be caused downstream in wxPython.

Thank you for checking this problem. Yes, I will report this to wxWidgets issue tracker, although I cannot provide a runnable c++ code now...

This issue will be fixed in the next wxWidgets version (maybe 3.2.1 or later) with this PR: https://github.com/wxWidgets/wxWidgets/pull/22651
