QCRITICAL: tst_QRhi::renderToWindowSimple(Null) Unsupported surfaceType(0), exiting.

This happens because webOS doesn't support raster pipeline (QSurface::RasterSurface value is 0):

QPlatformWindow *WebOSIntegration::createPlatformWindow(QWindow *window) const

{

// If one of conditions below is not satisfied,

// we should abort further initialization right away

// rather than trying a fallback which may lead an unexpected result.

// Note that abort() doesn't work properly as well for some reason,

// thus we call ::exit() instead to terminate the process gracefully.
