1606474 - Consider using a 16bit depth buffer

Status: RESOLVED WONTFIX

(Core :: Graphics: WebRender, enhancement, P3)

Description

[Jeff Muizelaar [:jrmuizel]]

The software WebRender backend currently only supports a 16bit depth buffer so this would be good for there. It should also reduce our memory bandwidth/ram requirements which should be good all around.

We talked about this briefly with Jeff, and I think it's a good idea. The only concern is having pages that have more than 65K primitives, in which case we'd be forced to either switch to transparent rendering for remaining primitives, or switch fully to a higher-resolution depth buffer.

This doesn't seem to offer much benefit on HW.
