Answer 1

Works on ubuntu (screenshot below).

According to this , the return value 3221225477 in hex is 0xC0000005 or STATUS_ACCESS_VIOLATION, which go reports as "invalid memory address or nil pointer dereference". So it may be an issue in the windows version of the Fyne GUI library.

This Fyne issue might be related .

Your source code works fine on macOS Mojave as well.

Though, I am getting a warning that 'NSOpenGLContext' has been explicitly marked deprecated in macOS 10.14. (This should not come in Windows.)

As Mark said, the return value 3221225477 in hex is 0xC0000005 ("Access violation"), it indicates that your program has terminated abnormally or crashed.
