Bug Description

There is a bug in mesa version 19.2.x where x>2, manifesting itself as window contents in large windows on 4K display renders with an incorrect vertical offset, making the desktop largely unusable for some customers.

The bug is fixed in latest 19.3 series and 20.0 rc series, but since Ubuntu 18.04.1 still uses 19.2 series, a manual backport is needed.

Please cherry-pick mesa master commit 451cf228d53ba8f51beb3dcf04370e126fb7ccb6 ("svga: Fix banded DMA upload") to fix the issue, alternatively switch to mesa 19.3 series.

Thanks,
