I am also seeing this same issue since updating Gapplin.
While this is being fixed, could we add preferences options to change quicklook/finder-preview background?:
This would make scanning through SVGs in Finder/Cover-Flow a very nice user experience.
At present, when there is a white SVG on a white background, nothing is seen in Finder. I encounter this a lot when making white icons that are placed on darker buttons to build scalable user-interfaces.
It would be nice if we could set a semi-transparent background with a repeating image like this:
Yesterday, I submitted a new Gapplin, v1.2.10, including this fix.
Sorry, but currently, I won't distribute Gapplin outside the MAS because of the limitation of my development time. The fix will be applied soon. Please wait for it.
That sounds interesting. Thank you for the suggestion.
However, in order to apply this fix quickly, I didn't implement it on 1.2.10.
I'm still not sure, what is the proper way to provide options for a quick look. It needs to be examined. So, I'll create a new issue for this feature later.
