Hi, I would like to know if there is any way we can improved the Android 8.0 graphic performance with i.MX6Q processor.

We recently ported Android 8.0 to our IMX6Q board with 2G RAM, and we noticed that the overall graphic performance is very slow. we can see obvious lagging from cursor movement. The lagging is more clear with LVDS output(1280x800). If we switch to HDMI 1280x720 output, the performance seems to be better, but it might be the monitor itself that helps the refresh rate. When we profile GPU performance as bar diagram on screen, LVDS and HDMI looks about the same.

We also tried playing with the cma and galcore.contiguousSize parameter in u-boot, but no help.

If you have any suggestion, please let me know. Anything appreciated!
