Does opengl=angle fix support for Win clients not having opengl 2.0 support?
-
We build a client using QtWebEngine from Python bindings. Unfortunately this client crashes on some windows clients not having native OpenGL 2.0 support (see debug below).
Should this work if I manage to compile qt on windows with opengl=angle?I already spent a whole day in trying compling qt from source on windows using msys2/mingw64 but fall from one trap into another without success and want to make sure the effort has even a chance of success...
Thanks!

finally - issue solved! At least on Windows 7 there are some DLLs missing QT is expecting for running OpenGL 2 shades. Solution is to (re) install DirectX End-User Runtimes (June 2010) on all Windows systems.
QT should check / fix this during installation on windows.background / longer answer on Stack Overflow: Does gt build with opengl=angle fix support for Windows clients not having opengl 2.0 support?
