ImGui has zero frame of lag for most behavios and one frame of lag for some behaviors.
At 60 FPS your experience should be pleasant. Consider that OS mouse cursors are typically drawn through
a specific hardware accelerated route and may feel smoother than other GPU rendered contents. You may
experiment with the io.MouseDrawCursor flag to request ImGui to draw a mouse cursor itself, to visualize
the lag between an hardware cursor and a software cursor. It might be beneficial to the user experience
to switch to a software rendered cursor when an interactive drag is in progress.
Also note that some setup or GPU drivers may be causing extra lag (possibly by enforcing triple buffering),
leaving you with no option but sadness (Intel GPU drivers were reported as such).
