Please review this bug report to Qt, which was determined to be the result of a regression in the Vivante Weston driver on the i.MX8M platform: https://bugreports.qt.io/browse/QTBUG-84226
The following call never returns:
eglSwapBuffers(m_eglDisplay, eglSurface);
Since this appears to be a regression in the vivante GL driver, is this something that the NXP GPU driver time can take a look at?
We have confirmed the occurrence of this bug on the i.MX8M Mini.
