Do you have real-world examples where the buffer damage would improve
performance?
Buffer damage is needed once the compositor no longer attaches shared
memory client buffers to a single texture. Normally, buffer damage would
include a region that got repaired + surface damage in buffer-local
coordinates.
Note, many clients now use some kind of hardware acceleration, which
wouldn't benefit from this optimization.
There are still too many popular applications that use QtWidgets, for
example, qBittorrent, Konsole, Telegram (Desktop), etc. They all provide
shared memory buffers.
Cheers,
Vlad
