1526856 - Reduce per-frame GPU cache uploads.

Status: RESOLVED FIXED

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

Attachment: Bug 1526856 - Reduce GPU cache uploads a bit.

By retaining a global GPU cache handle for a dummy image block, we
can reduce the per-frame GPU cache uploads quite a bit, which
helps with compositor time.

I think this might be a rebase issue with another patch that is currently in the queue - I'll wait until that lands and then re-submit this.

Comment 5

[Kartikaya Gupta (email:[e-mail])]

Sounds like a rebase conflict with bug 1526593. It's possible to pull autoland and rebase on top of that if you don't want to wait until it reaches m-c. Ping me if you want me to walk you through it.

[Glenn Watson [:gw]]

Ah, that makes sense, thanks. I'll just wait and land it tomorrow - it's a small optimization I noticed while working on other things, no urgency.
