G1X White Spots
Not had spots like yours, but I have noticed quite bad highlight clipping with mine.
Running at 200%DR helps, but it is still a problem to watch out for.
This mode unfortunately brings up shadow noise as well.
Dpreview mentions this. Other reviews have noticed this.
Can't understand why such a large sensor should behave like this.
