OpenGL is definitely possible on Sailfish, it is how all the UI is rendered :)
For the GL rendering to be visible, you need to make sure to not clear it or
draw anything on top of it. Does your squircle implementation still disable
clearing of the QQuickView? Or perhaps your QML has a fullscreen rectangle
which obscures the GL rendering done into the background?
