I've just tried new OpenGL driver using the command 'raspi-config' but anyone of the new options work:
- GL (Full KMS): all the letters and images show corrupted.
- GL (Fake KMS): I can see right the letters and images but mouse pointer is not aligned, I click in another point where the mouse pointer is.
- If I disable overscan the raspi screen is much bigger than TV screen.
This is a raspberry pi 2 connected to an LCD 32" HD Ready TV set by HDMI.
It runs ok in legacy non-GL mode.
I try a fresh installation of the new Raspbian Stretch, but these problems also happened in old raspbian jessie.
