Hi, I recently installed LyX 2.4.0 on macOS 12.7.5(intel) and found that scrolling plain-text (revtex4-2, with several sections with math, comments and LyX note plus an appendix but no figures) documents created by LyX 2.3.7 tends to lag. This can be reproduced by quickly scrolling the document up and down by 3-5 times. Sometimes the program would stop responding and recover after a few seconds. Converting the document to LyX 2.4 format with lyx2lyx does not help. Also this behaviour occurs with both Qt5 and Qt6 libraries (Qt 5.15.12 and Qt 6.6.2 from Homebrew). This did not happen to LyX 2.3.7.
Thanks! Best, Hung-Tzu
