1403971 - Update webrender to aa81aebba2c1b8ff8af5d40796154d66349fd131

Status: RESOLVED FIXED

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

Description

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

+++ This bug was initially created as a clone of Bug #1402321 +++

I'm filing this as a placeholder bug for the next webrender update. I may be running a cron script [1] that does try pushes with webrender update attempts, so that we can track build/test breakages introduced by webrender on a rolling basis. This bug will hold the try push links as well as dependencies filed for those breakages, so that we have a better idea going into the update of what needs fixing. I might abort the cron job because once things get too far out of sync it's hard to fully automate fixing all the breakages.

When we are ready to actually land the update, we can rename this bug and use it for the update, and then file a new bug for the next "future update".

There's some fail with this panic:

thread '<unnamed>' panicked at 'assertion failed: pass.max_used_color_target_size.width > 0', /builds/worker/workspace/build/src/gfx/webrender/src/renderer.rs:3043

Regression range:

* 39e6038c Auto merge of #1758 - glennw:small-target, r=kvark
* 3a5b7923 Initialize render targets to the required size, saving memory and clear time.

More of the same. And there's an opt R4 failure that I thought was intermittent but seems to have persisted. So that would have the same regression range as noted in comment 1.

The reftest output was broken recently so that some of those try pushes don't show anything in the reftest analyzer, but it's fixed now so the most recent try push does show stuff. Here's a link for the R4 failure:

https://hg.mozilla.org/mozilla-central/raw-file/tip/layout/tools/reftest/reftest-analyzer.xhtml#logurl=https://queue.taskcluster.net/v1/task/JqwZiFZMQayAE8Pj3ZLEVQ/runs/0/artifacts/public/logs/live_backing.log&only_show_unexpected=1

This looks like it can just be fuzzed away, since visually the pages look the same. The test was already marked fuzzy-if(webrender,8-8,242-242) and we need to expand that to 8-8,255-255.

The upstream change in servo/webrender#1758 was reverted, so these are mostly green except for the unexpected-pass in R4 which is a result of the increase in fuzziness that I added to my patch queue. If I remove that it should be back to green.
