--- Comment #1 from Paul Gofman gofmanp@gmail.com --- Thanks for reporting and bisecting!
What I am seeing as problems is: - The size of combobox with font sizes in formatting toolbar is a bit bigger than font selection control right when those appear (they are the same size on Windows and with blamed commit reverted); - When switching between tabs so that the text formatting toolbar disappear / appear back the outer toolbar is getting smaller or bigger, also resizing other docked windows (also doesn't happen on Windows and with the commit reverted).
I found nothing wrong so far in the blamed commit, although the problem is still in combo box implementation it looks like. The combo boxes end up with wrong size during creation from within WM_CREATE handling (which involves querying WM_MEASUREITEM since those are CBS_OWNERDRAWFIXED comboboxes). Out interpretation of MEASUREITEMSTRUCT.itemHeight turns out to be off a few pixels. Previously when WM_SETFONT was causing window resize that was accidentally getting fixed up but that's not how that works on Windows.
I sent MR upstream: https://gitlab.winehq.org/wine/wine/-/merge_requests/9427
Could you please check if that helps if possible (and also confirm that I understood the problems introduced by the blamed commit correctly)?
