Since some users prefer the insertion pointer to reflect the same as the Compositor a choice is available. For playing forward, there is a preference option which results in what looks like 1 was added to the frame displayed in the Compositor window. To enable this mode, check the box \texttt{Always show next frame}, and this will be saved to \texttt{.bcast5}. The option checkbox is in the \texttt{Settings $\rightarrow$ Preferences $\rightarrow$ Appearance} tab and when checked, any forward \textit{plays} in the Compositor window show the same frame as you would with a seek. Reverse plays and plays using a selection or In/Out pointers (with \texttt{Ctrl}) work the same as without this preference set. But you will no longer see the odd behavior where if you frame advance forward and then frame advance backward, the displayed frame does not change -- instead it will change and look more natural.
A color indicator that shows in the main track canvas timeline and the compositor timeline reminds the user which mode is currently active. The cursor in the compositor turns \textit{red} for default mode and \textit{white} for \textit{Always show next frame} mode. The top portion of the insertion cursor in the track canvas mirrors this, with red for default and white otherwise.
-Figure~\ref{fig:cursor01} using the default \textit{playing} method where the frame in the compositor is the one that was just played; in this case play was in the forward direction. Note that the insertion pointer in the main track canvas shows 01:20 but the compositor show 01:19 so you know what you last saw. Also, the cursor/cursor tops in both windows is red.\todo{I make copy/paste from your examples; but no arrow is displayed}

The cause of the issue is that X11 is RGB only and it is used to draw the \textit{refresh frame}. So single step is always drawn in RGB. To make a YUV frame into RGB, a color model transfer function is used. The math equations are based on color\_space and color\_range. In this case, color\_range is the cause of the \textit{gray} offset. The \textit{YUV mpeg} color range is $[16..235]$ for Y, $[16..240]$ for UV, and the color range used by \textit{YUV jpeg} is $[0..255]$ for YUV.

The mpeg YUV color range $[16..235]$ looks sort of like an old TV if it is viewed on a display with jpeg range $[0..255]$. A common expression for the short \textit{mpeg} color range is \textit{compressed} color range. If you are using color compressed data with no display decompression, or using uncompressed data and the display is configured to use compression, the color range will appear \textit{squished} or \textit{stretched}, as too gray or too much contrast.
The \texttt{use X11 direct when possible} preference with X11 as your video driver, generally means that you value speed over color range. When you use this feature and the color range preference is mismatched, the color switch offsets will still appear. This is a personal choice solely for improved speed.
\item[YUV color range] default choice is JPEG, alternate is MPEG
