Field Documentation

cellsDrawnAtWrongFontSize

std::atomic<long> Configuration::PerformanceStats::cellsDrawnAtWrongFontSize {0}

How many cells were drawn at a different font size than they were laid out with.

Nonzero means a cell was re-measured behind its owner's back (e.g. a lazy GetWidth() repair or a draw-list recalculation at the top-level font size) after the surrounding cells had already cached extents based on the owner-dictated size: the visible symptom is text in 2D fractions shown at full size and parentheses narrower than their content.

worksheetFullRepaints

std::atomic<long> Configuration::PerformanceStats::worksheetFullRepaints {0}

How many of those repaints covered (nearly) the whole visible worksheet.

Full repaints re-render every visible cell's text, so they are the expensive kind: this counter rising while the user merely moves the mouse or a cursor blinks reproduces the "constant full redraws" performance bug class (e.g. the composited GTK overlay scrollbar).
