I am using Freescale Linux 4.9.88, Yocto-Rocko, X11 image.
The GPU Vivante driver is 6.2.4 p1.
In landscape mode, everything is correct. But when I use xrandr and rotate the screen to have portrait mode, it seems memory is corrupted. Jyst moveing the mouse shows the problem. In attachment, you can find the pictures of the bugs.
Is rotation supported in new Vivante 6.2.4 in X11? In old version(5.0.11) I had no problem.
Thanks in advance
