SUMMARY digiKam 7.3.0 snapshot 24.5.2021 crashes on a Windows 7 system that has no support for OpenGL. I open View --> Presentation and inside next dialog I press Start. A popup window is shown: No support for OpenGL - which is correct. One second later - GUI has gone without any further message or - another popup is display: digiKam does not work properly anymore. Here only OK can be pressed. STEPS TO REPRODUCE 1. 2. 3. OBSERVED RESULT EXPECTED RESULT SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
I know the problem under Windows. We have to see if there is another way to safely recognize OpenGL beforehand. The creation of a Qt-OpenGL widget and query whether OpenGL is available leads to a crash when exiting, no OpenGL functions were executed. Maik
Herb, digiKam 7.4.0 release is published. Can you check if problem still reproducible ? Thanks in advance Gilles Caulier
@herb, digiKam 8.0.0 is out. Problem still reproducible with this release ? Gilles Caulier
@herb, This problem still reproducible with the new digiKam 8.2.0 pre-release Windows installer available at usual place: https://files.kde.org/digikam/ This new bundle is based on last Qt framework 5.15.11 and KDE framework 5.110. Thanks in advance Gilles Caulier
Hi Maik, With the native VCPKG build + Qt6, is the OpenGL problem remain ? Note that Angle API is used as native by Qt6 : https://chromium.googlesource.com/angle/angle/+/main/README.md This want certainly means that DirectX dll needs to be present on the Windows system to works properly. I think with a basic Windows 10, DirectX runtime is not present. If necessary, and if a redistributable version exists, DirectX dlls can be included in the bundle. Gilles
As this one : https://www.microsoft.com/en-us/download/details.aspx?id=35 This is the DirectX 2022 runtime. As annoted in this page : "Microsoft DirectX® is already included in Windows XP Service Pack 2, Windows Server 2003 Service Pack 1, Windows Vista, Windows 7, Windows 8.0, Windows 8.1, Windows 10, and Windows Server equivalents. This DirectX End-User Runtime does not change the version of DirectX, but does install a number of optional side-by-side technologies from the legacy DirectX SDK that are used by some older games." I don't know really if this runtime is necessary on client computer. Gilles
