Created attachment 160554 [details] icons scale ignored SUMMARY I use a 4K screen. I have Digikam configured to display the largest icons, just like ShowFoto. However, if I open ShowFoto independently, the icons are very small, not respecting the settings assigned for my HiDPI display. STEPS TO REPRODUCE 1. Select a image in Dolphin 2. Click with right mouse button 3. Select "Open with" 4. Choose "shoFoto" OBSERVED RESULT Icons are so small that can't use them EXPECTED RESULT To show same scale for icons than Digikam SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20230718 KDE Plasma Version: 5.27.6 KDE Frameworks Version: 5.108.0 Qt Version: 5.15.10 Kernel Version: 6.4.3-1-default (64-bit) Graphics Platform: X11 Processors: 4 × Intel® Core™ i5-6600K CPU @ 3.50GHz Memory: 31.3 GiB of RAM Graphics Processor: NVIDIA GeForce GTX 1050 Ti/PCIe/SSE2 ADDITIONAL INFORMATION
Showfoto is a stand alone application compared to digiKam. Showfoto don't knows the digiKam settings and has an own configuration. In other words, got to Showfoto Setup dialog and turn on right options to support 4K screens. Gilles Caulier
Another word here about openSUSE Tumbleweed, which I also use. With my digiKam developer version, the settings for screen factor scaling and HiDPI icons no longer have any effect here. It looks like openSUSE has patched the Qt packages accordingly, as going forward with Qt6 these options will always be enabled. I can't reproduce the problem, when I start Showfoto from Gwenview, the icons are scaled correctly. Maik
I always thought that ShowFoto was integrated in DK and that they shared their configuration, especially when it happens, as I said, that it only respects the size of the icons when launched from Digikam (F4 key). As you suggested, I enabled in showFoto "Preferences, Other, System" HiDPI parameter and it's working. Thank you for clarifying how the detail that showFoto is independent of DigiKam.
