--- Comment #21 from Kristian Karl <kristian.hermann.k...@gmail.com> --- I tested the latest appimage of Digikam (digikam-5.9.0-01-x86-64.appimage) on the latest KUbuntu (18-04.1) version on Virtualbox. 1) I used images from http://cswww.essex.ac.uk/mv/allfaces/faces94.html http://cswww.essex.ac.uk/mv/allfaces/faces94.zip 2) I then let Digikam scan for faces on all the images 3) I open People view, and select the tag unknown 4) Select a Flat List in the View | Separate Items 4) I maximize my VirtualBox window in my 3840x2160 screen, and then maximize Digikam in VirtualBox. 5) I click on the People view tab (hide it), so I can maximize the number of thumbnails in the window. 6) Adjust thumbnail sizes to smallest possible. I get flicker. Using the steps above should be enough to reproduce the flicker on any 4k screen. If an 4K screen is not available, the VirtualBox window could be made very large by just increasing the size of that window, and moving it outside, until a very large window is made, the maximize the Digikam window. I think the problem perhaps is related to the actual size of the Digikam window, and the number of people thumbnails being displayed? -- You are receiving this mail because: You are watching all bug changes.
