Thanks to the remote tests that I made with aminor00 and the interesting screenshots and comments sent by LR9215, I found where the bug comes from in OpenGL AMD driver, and even better, how to fix it without waiting for AMD correction.
Please, use the version [s]7.0.2h[/s], [s]7.0.2i[/s], 7.1 and confirm it works for you.
