windows: Introduce a built-in GPU blacklist
Use a built-in JSON file in case the QT_OPENGL_BUGLIST environment variable is not set. When QT_OPENGL_BUGLIST is set, the built-in list is ignored. To make the implementation simpler and more readable, some of the code in QWindowsOpenGLTester is reshuffled a bit. It also caches the results now, so it is safe and fast to call supportedRenderers() and friends multiple times. The blacklist currently contains the Intel card from QTBUG-43263 (Intel GMA / HD3000 ?) and may also apply to QTBUG-42240. [ChangeLog][QtGui] Qt now contains a built-in GPU driver blacklist for Windows that disables the usage of desktop OpenGL with some older cards that are known to be unstable with opengl32.dll. Task-number: QTBUG-42240 Task-number: QTBUG-43263 Change-Id: I1ecd65b51fca77925317d52048e7ab01d9b8797c Reviewed-by: Friedemann Kleint <>
