Comment (by pege):

 I ran into the same issue. I changed devPixelsPerPx to 1.25 and
 Panopticlick now tells me that my screen resolution is 1001x900x24. Yet
 what worries me really is that Panopticlick tells me that one in 90,000
 browsers have the same fingerprint. Considering how frequently that
 fingerprint appears, I wonder if this issue should be handled with higher
 priority. I also wonder if devPixelsPerPx needs to be set manually. Could
 auto-detection of high DPI result in the same outcome? I doubt this has
 been changed manually in as many browsers as Panoticlick reports.

 Btw, I also tested this in Firefox Nightly with
 privacy.resistFingerprinting enabled, same outcome.
