[REG 6.2.11 -> 6.2.12] Qt Composition Mode - Animation Stops When "Use OpenGL" is enabled

Description:-

The Qt Composition Mode example fails to use OpenGL as a renderer backend on linux. Animation stops as soon as "Use OpenGL" is enabled.

Steps to Reproduce:

1. Build and Run Composition Modes on linux.
2. click "Animated"
3. click "Use OpenGL".

Expected Behavior: Upon clicking the "Use OpenGL" button, the animation should seamlessly transition to utilizing OpenGL rendering without halting animation.

Actual Behavior: The animation abruptly halts its rotation. 

Additional Information:- This issue is not reproducible with other versions of Qt.
