Panning called updateOverlay() three times per mouse move: once for each scrollbar's valueChanged -> onScroll(), then once explicitly. Zooming was the same. Every one of those tore down and rebuilt every overlay item. Suppress onScroll() for the duration of the gesture instead, and let the gesture do its single rebuild at the end. Note this cannot be done by blocking the scrollbars' signals: QAbstractScrollArea drives the actual scrolling off valueChanged, so blocking it would stop the view moving at all. updateOverlay() also refreshed the image item unconditionally, which marks the whole item dirty and forces a full-viewport repaint even though pan and zoom never change the pixels. Track whether RenderImage has run since the last refresh and skip it otherwise. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
