--- Comment #3 from Rafał Mużyło galtgendo@o2.pl --- Looking at the commit, combined with that both native comctl32 doesn't help and that TAB_SetMinTabWidth isn't being called, just TAB_SetItemBounds - the later only interested with width (unless tab is vertical) - makes me suspect the commit is actually wrong, the change simply had a side effect (perhaps GetTextMetrics after a font change is triggering some extra internal recalculations ?).
