Some platform plugins, eglfs in particular, support setting swapInterval via 
environment variables (QT_QPA_EGLFS_SWAPINTERVAL). Others do not. It should 
definitely be added to QSurfaceFormat. It might be too late for 5.2 though.

Best regards,

Subject: [Interest] QSurfaceFormat and swapInterval

QGLFormat exposes a swapInterval property which can be used to enable vertical 
synchronization (v-sync) to avoid screen tearing.
Why does QSurfaceFormat not expose this property? Currently, there is no direct 
way to enable v-sync with QWindow, while QGLWidget did not have this problem.
What is the rationale for leaving this out?
