https://jrmuizel.github.io/webrender/slow/coulds.html It looks like we're spending a bunch of time blurring.
The url should be https://jrmuizel.github.io/webrender/slow/clouds.html
You can assign this one to me, if you like. I imagine we'll want to add image blurs to the list of items we pre-render to the texture cache, or something similar.

I profiled this briefly - in this case it's actually text shadows being used for the effect. We'll want to cache text-shadow blurs, just as we do for box-shadows.
Could bug 1452489 be a (long winded) duplicate of this?
We can't release this to the field, but we can let this ride to beta.

The initial patch for picture caching on text shadows is https://github.com/servo/webrender/pull/3270. The commit mentions: This brings the GPU time in the cloud ad  from 43 ms down to 8 ms for me. This is still higher than we want, due to the very high number of cached text shadows that get composited. This should be resolved as we support nested picture caching. I think it's probably OK to verify and mark this as fixed once that lands, as it makes the performance very usable. It's just not as fast as we want / expect it to be in the future.
