We are experiencing strange graphics error on our device with AM335x and Android 4.4.4.
The problems begin some time after booting, sometimes very fast, sometimes after more time.
The effects are black areas on the screen or missing textures(?), see screenshots.
After these effecs occurred, the device becomes more and more unresponsive and sometimes locks up.
In two cases of lockups we were able to capture kernel logs, both show (different) errors from the
SGX kernel driver. The problem is (supposedly) limited to newer versions of our software,
but there are no differences between in the obviuosly relevant parts of the software (kernel,
OpenGL driver, Android framework).
The effects seem to be coupled to previous usage of OpenGL, they first appear (at least visually)
after using an app which makes use of OpenGL.
Has anyone seen problems of this kind? Or any hints where to look further?
