Some items near windows left and right edge that used to be clipped + may be partly more visible. (#3312, #7540, #3756, #6170, #6365) +- Windows: Fixed subsequent Begin() append calls from setting last item information + for title bar, making it impossible to use IsItemHovered() on a Begin()-to-append, + and causing issue bypassing hover detection on collapsed windows. (#7506, #823) - Fonts: Fixed font ascent and descent calculation when a font hits exact integer values. It is possible that some prior manual use of ImFontConfig::GlyphOffset may become duplicate with this fix.
