My graphics Drivers for the Radeon 430 card and intel UHD 620 are uptodate and the opengl extensions viewer says that opengl 4.6 is supported and opengl apps compiled under mingw64 in MSYS2 run fine. When I tried to compile the point sprites example from opengl redbook 9th ed. using cygwin g++ and linking using -lX11 instead of windows I get an error of being unable to create context opengl 4.0-4.6. Only when I set opengl context to 3.3 does the program run and no core dump is generated. But of course I get a black window since the program needs at least opengl 4.3 to run. I'm really not sure what to do to make cygwin aware of my graphics cards capabilities?hisham...

maybe you need to install libGL-devel ?
without further info and a simple test case we are in the dark of
where is your problem.
