The white, black and gray only options disable checks and the transparency will be shown as a solid black, white, or gray color.
Check Size
Sets the size of the checks in the pattern that indicates transparency.
If you have set the check type to white, gray, or black only, then the size
will have no effect what so ever.
12.5.2 8-Bit Displays
Install Colormap
If you are working on an 8-Bit display, the GdkRGB subsystem of GDK will automatically
figure out if it needs to install its own colormap or not. Since GIMP’s plug-ins are all
separate processes with their own instances of GdkRGB, it may happen that GIMP and
some of its Plug-Ins choose different colormaps, resulting in color flickering.
If you encounter such behaviour, you can activate “Install Colormap” in order to force
GIMP and its plug-ins to use the same colormap.
Colormap Cycling
If you are working on an 8-Bit display, you can display the “Marching Ants” which show
the current selection by means of a rotating colormap instead of re-drawing them all the
time.
