The queue-level fix for the live-follow OOM bounded how many datasets are in flight, but not what each tick costs. Three handlers did full-dataset or full-detector work per tick regardless of whether their window was open: - the calibration window copied the whole pixel mask (GetMask returns a reference; it was taken by value), memcpy'd it and ran a full-resolution recolour on the GUI thread; - the image-list window rebuilt one row of eight QStandardItems per image, and then repainted every cell of the model on every frame to move a one-row highlight; - the dataset-info plot was rebuilt twice per tick, because setCurrentIndex fires currentIndexChanged -> comboBoxSelected -> UpdatePlot and the caller then called UpdatePlot again. The first two now defer to showEvent while hidden, following the pattern JFJochViewerReciprocalSpaceWindow::rebuildGL already uses; the highlight repaints only the two rows that change; and the combo is blocked around setCurrentIndex so the plot is built once.
