It is.

I thought [1] was already applied, but it seems it was only RBd.

I can either apply [1] and then add this on top, so the two commits can 
be reverted separately if this one breaks something, or squash [1] into 
this patch and send V2. Which one do you prefer ?

The [1] fixes a real nasty issue with DPI output which causes visible 
image corruption, so I would like to have [1] in, but it is obviously 
not perfect.
