1716794 - Picture cache tiles are not partially invalidated on Mali-400

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, defect)

Description

[Jamie Nicol [:jnicol]]

Currently we prevent partial picture cache tile invalidation on all Mali devices to workaround a driver bug. (See bug 1663355 and bug 1691955.) This driver bug affects some Mali-G and Mali-T devices, but currently we apply the workaround for any Mali GPU.

Mali-400 may or may not be affected by the same driver bug, but since it uses software webrender we certainly do not need to apply this workaround.

Allowing partial invalidation should allow for smaller texture uploads.
