Created attachment 164701 [details] The browser and the image thumbnails are shrinked to a small portion of a white background. Also appears some strange squares on the white surface. SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. Open digikam. It opens in the primary FullHD monitor. 2. Drag digikam window with mouse to the secondary 4K monitor or 3. Tried to move with keyboard shortcut (Windows button+arrow) repeated more times caused Blue Screen OBSERVED RESULT digikam window is shrinked inside a bigger white window on the secondary monitor. when I switch to full size window, the appearance reamains the same. When I drag back the window to the first FullHD monitor, the appearance is ok again. EXPECTED RESULT Moving digikam to another monitor with different resolution, have to mantain the original window resolution, and switching to the whole monitor cover the entire screen with no white, empty surface. SOFTWARE/OS VERSIONS Windows: 10 Qt Version: 6.6.0 ADDITIONAL INFORMATION
We made many changes in bug 477795 so that the changed device pixel ratio is passed on to the required components. Although your screenshot looks strange, please test the latest digiKam-8.3.0 pre-version from here: https://files.kde.org/digikam/ Maik
I tried the suggeste 8.3 version but the result is the same
It will be a problem with your graphics hardware/drivers. If you have the opportunity to update the driver, please do so. I tested it again here today, with an Intel Mini PC (Windows 11) with Intel Graphics and 2x HDMI output. A TV screen with 4k resolution and 200% scaling and an HD screen with 100% scaling. I can drag digiKam between the two screens without any problems and it adjusts without any problems. You can test one more thing, please remove the OpenGL32.dll in the C:\Program Files\digiKam\ directory to see if there is a change. Maik
Tried to remove that dll and installed the latest nvidia driver and no change, the same problem...
I also changed my 4K monitor to be the primary and digikam opens directly on that screen but it looks in the same way. Whwn I move on the another (now secondary) FullHD monitor, it's ok again.
I think we can't solve this problem. We will have to wait and see how things develop with new Qt6 versions. Maik

A new digiKam-8.3.0 pre-version is available. In the digiKam settings under Miscellaneous-> System, activate the option to force software OpenGL. Restart digiKam and test whether the problem still occurs in the 4K screen. https://files.kde.org/digikam/ Maik
With the previous pre-version I made some settings in Compatibility mode, at "Change High DPI settiings" section. At "High DPI scaling override" checked the "System" option. Now it works as expected.
Can you please try with the current version without the compatible mode options set. And only use the digiKam option to force software OpenGL? Maik
Installed the new version and digikam window behave normal when switch between the two monitors, but the menu titles are compressed on the 4K monitor. Not visible all words, both in top main menu and in the right side menu. When enable at "High DPI scaling override" section the "System" option the menus are ok again.
Ok, I've already noticed the menu items, this is a KF6 component. We'll keep an eye on it, I'll close the bug now. Maik
