In newly-flashed 64-bit bookworm raspberrypi OS, chromium-browser flashes between black and white with VNC (similar to viewtopic.php?p=2140657&hilit=Pi+3+and+ ... y#p2140397) in headless Pi 3B (tested resolutions: 1920x1080, 1024x768, 800x600) but works fine when connected to an HDMI external monitor (1920x1080). Disable GPU acceleration can solve problem but prefer to have the acceleration. On the other hand, Firefox-esr has no problem through VNC. Also, no such problem in bullseye. The issue seems to be chromium and RealVNC associated.
