1664478 - Blend modes and other effects on a single image force an extra intermediate target

Status: NEW

(Core :: Graphics: WebRender, defect, P2)

Description

[Nicolas Silva [:nical]]

For example on the humble bundle home page https://www.humblebundle.com/ each game's image has a brightness filter applied to it which causes webrender to first render the image into an intermediate target and then use that as the source of the blend shader.

We should run the blend shader directly off of the texture cache instead of adding a costly intermediate target.

in addition it appears that the blend shader is done in the alpha pass even though the image is known to be entirely opaque (jpg).
