CRX-24[Z] Transparent Overlay Visuals
The default number of colormap entries in the overlay visual for the CRX-24[Z] is 255. Entry 255 is
excluded because its value is hard-coded to transparent (that is, show the image planes).
This may have the following two consequences for X11 applications running in the overlay planes (the
default visual):
• Clients attempting to allocate 256 entries do not have their request granted.
• Clients requesting (via XAllocNamedColor) the rgb.txt value of "Transparent" are not returned
entry 255.
This default behavior can be changed by setting the CountTransparentInOverlayVisual screen option.
