Framebuffer depth and colormaps
Depth 24 is the recommended depth. The benefit is that with the TrueColor visual,
applications have a large 16M color palette available. Because the TrueColor colormap
is read only, it can be shared among multiple applications without any color flashing
problems.
The depth 8 framebuffer configuration is mainly intended for backwards compatibility.
Some older applications, or applications that want to use colormap tricks may insist
on using the PseudoColor visual. The PseudoColor colormap is read/write and has 256
colors. Each application can have a private colormap if requested, or multiple
applications can share the same default colormap.
An issue with the PseudoColor visual is that there is only one hardware colormap. If
there are multiple applications running, each with its own private logical colormap,
they have to share the single hardware colormap. Only one application, the one that
has the focus, has the correct colors. Others do not. You may observe color “flashing”
when you move focus between different windows. If PseudoColor applications can
share the same default colormap without running out of colors, the color flashing does
not occur.
