This seems to only happen on dual-monitor configurations, most frequently on w1064-2qxl but also regularly on w7u-2qxl.

--- Comment #1 from Esme Povirk madewokherd@gmail.com --- 0024 (the message after WM_WINDOWPOSCHANGING) is WM_GETMINMAXINFO

--- Comment #2 from Esme Povirk madewokherd@gmail.com --- This was NOT fixed by https://gitlab.winehq.org/wine/wine/-/merge_requests/3862
It's odd because these should be no-ops. Size and position are unchanged, along with SWP_NOACTIVATE|SWP_NOZORDER. Documentation for SetWindowPos suggests something else may have been changed which requires a SetWindowPos call, but it advises SWP_NOMOVE|SWP_NOSIZE|SWP_NOZORDER|SWP_FRAMECHANGED in that case.
I don't know what we could be doing to trigger this, but I also don't see this particular message sequence happening in other circumstances, so I guess it makes sense to add these as optional?
