Had the same problem with an RPi 5 running bookworm with X11 and RealVNC with no monitor attached - lags of several seconds in Chromium when scrolling or typing into the search bar which made it unusable for me in its intended role as a Linux desktop machine. Happily I can confirm that disabling acceleration in Chromium as suggested above gets rid of the lag, as does connecting to an HDMI monitor even if that monitor is switched off or is on but connected to a different system.
So this works for me now, but the problem appears to be undocumented and it took a while to find a workaround (and also the problem might affect applications other than Chromium?). I couldn't find a recent open issue - is this being looked at?
