When a certain configuration is requested explicitly, no checks are done at application startup, that is, the system-provided opengl32.dll will not be examined. Qt::AA_UseSoftwareOpenGL Equivalent to setting QT_OPENGL to software.Qt::AA_UseOpenGLES Has no effect in Qt 6.Qt::AA_UseDesktopOpenGL Equivalent to setting QT_OPENGL to desktop.The loading mechanism can be configured through the QT_OPENGL environment variable and the following application attributes: If these are present, opengl32.dll is used, otherwise it attempts to load opengl32sw.dll. By default, Qt will determine whether the system's opengl32.dll provides OpenGL 2 functions. Instead, the library is chosen and loaded at runtime. When configured with -opengl dynamic, neither Qt nor the applications built using qmake or CMake will link to opengl32.lib.
#OPENGL 2.0 ACCELERATED GRAPHICS SOFTWARE#
The pre-built Qt packages ship a build of Mesa llvmpipe, a software rasterizer implementation of OpenGL, under that name. When a given environment fails to provide a proper OpenGL 2.0 implementation, it will fall back automatically to load an alternative to opengl32.dll, the default name of which is opengl32sw.dll. This configuration is the most flexible because no dependencies or assumptions are hardcoded about the OpenGL implementation during build time. This mode is the default, and can be explicitly requested by passing -opengl dynamic to the configure script. Qt supports choosing and loading the OpenGL implementation at runtime. The following sections cover some OpenGL specifics of a Qt build. While not the default for Qt Quick, OpenGL is still commonly used in many Qt applications, for example in QWidget-based applications building on QOpenGLWindow or QOpenGLWidget.
#OPENGL 2.0 ACCELERATED GRAPHICS DRIVER#
To request using Vulkan or OpenGL, both of which require a Vulkan or OpenGL driver to be installed, set the environment variable QSG_RHI_BACKEND to vulkan or opengl, or use the equivalent C++ API in main(). To force using Direct3D's software rasterizer (WARP), set the environment variable QSG_RHI_PREFER_SOFTWARE_RENDERER to 1. ANGLE is no longer shipped with Qt in Qt 6. This is different from Qt 5, where the default was OpenGL, either directly, or through ANGLE, an OpenGL to Direct3D translator.
#OPENGL 2.0 ACCELERATED GRAPHICS WINDOWS#
As of Qt 6, the default for Qt Quick on Windows is Direct3D 11. If there is, then WebGL is enabled, but if there is an error message indicating there is a block, then your graphics driver is blacklisted.For Qt Quick to work, a graphics driver that provides Direct 3D 11.1, Vulkan 1.0, or OpenGL 2.1 or higher is required. Go to the Graphics table and check if there is a graphics card manufacture, model, and drive in the Driver Renderer section.
If the value for webgl.disabled is false, next you should inspect the status of WebGL at about:support. Go to about:config and search for webgl.disabled in the search bar to ensure its value is false. If hardware acceleration is currently enabled, inspect the status of WebGL under the Graphics Feature Status section at edge://gpu/. Check to ensure User hardware acceleration when available is enabled in the System settings. or go to edge://settings/system to open the browser settings. If hardware acceleration is currently enabled, inspect the status of WebGL under the Graphics Feature Status section at about:gpu. Go to the System section and ensure that Use hardware acceleration when available is enabled. Expand the Advanced options and select Browser. Select Opera -> Preferences. or go to about:config to open the browser settings. One way to determine if this is the case is to access WeVideo in an incognito window that has all extensions disabled. Please also check to ensure you are not using any extension that may be disabling WebGL.

You may need to update your display drivers and then go back to the gpu again to further troubleshoot.
If you have a display driver older than 2010, it may be the cause of the issue. This list will provide details on what you may need to do next. If the status of WebGL does not show Hardware accelerated, please scroll down the page and refer to the Problems Detected list to determine why hardware acceleration is unavailable. If hardware acceleration is currently enabled, inspect the status of WebGL under the Graphics Feature Status section at chrome://gpu/. Navigate to chrome://settings/system and check to ensure that Use hardware acceleration when available is enabled. Refer below to find out if your browser currently has hardware acceleration enabled.
To use WeVideo, your device must have WebGL enabled.
