Title:
[enhancement] android hwc overlay could optimize movement of surfaces
without buffer update
Status in Mir:
Triaged
Status in mir package in Ubuntu:
Triaged
Bug description:
Currently, we check in the hwc code that a buffer has changed from the
previous commit to avoid submitting the same thing to the screen
twice. This does not factor in changes to the the screen positioning.
If it did, we could optimize a few more scenarios using 2d
acceleration.
This won't cause rendering glitches, just a bit worse performance in
some non-critical-path scenarios.
