--- Comment #4 from k...@binkmail.com --- This problem went away at some point but has returned even worse in 7.5 and the most recent 7.6. Here hopefully https://ufile.io/er79cpxm will get you a photoshop saved16bit tiff file. I have a dozen applications on this machine which can load this file in less than 2 seconds. Digikam takes 21 seconds to view it or generate a thumbnail. Larger files with more photoshop baggage are even more ridiculously slow. A 531MB file which windows paint can load in about 3 seconds takes Digikam 142 seconds to view or to generate a thumbnail. During these long waits Digikam uses 100% of a CPU core (sometimes multiple cores presumably generating thumbnails in parallel). A stack trace of the Digikam thread taking all the CPU includes libtiff. A couple of the other applications which load these files without problem use earlier versions of libtiff. -- You are receiving this mail because: You are watching all bug changes.
