At least, it can handle x-pixman=0 fine when !CONFIG_PIXMAN then. Btw, looking at it, it seems it should be DEFINE_PROP_BIT instead.

Sure, but we could have more explicitly different BIT properties ("x-pixman-fill", "x-pixman-blit", "x-pixman-overlap-blit"). thanks

That was also proposed when I've added it and concluded that we don't want that. This is a debug option for experts and adding a lot of experimental options for that that are also harder to type is not an improvement so having just a value is fine. Regards, BALATON Zoltan
