case OVERLAY_FLASH:
/*
* A compositor will not send a frame callback for our main
* window if it is fully occluded (for example, by a fully
* opaque overlay...). This causes the overlay to stuck.
*
* For regular buffers, it _should_ be enough to *not* hint
* the compositor it's opaque. But at least some compositor
* special cases single-pixel buffers, and actually look at
* their pixel value.
*
* Thus, we have two options: implement frame callback
* handling for the overlay sub-surface, or ensure we don't
* use a fully opaque surface. Since no overlays are fully
* opaque by default, and the flash surface is the only one
* that can be configured to be opaque (colors.flash-alpha),
* and since adding frame callback handling adds a lot of
* boilerplate code... let's go with the simpler solution of
* not allowing colors.flash-alpha to be 1.0.
