Status: ASSIGNED

(Core :: CSS Parsing and Computation, defect, P3)

Description

[radio]

Attachment: bug.zip

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20171206182557

Steps to reproduce:

Loop through some  ctx.font  and  ctx.fillText on canvas


Actual results:

open page, move mouse off page and then just wait.
after a little time Thread goes 100% cpu
if you move the mouse over the page it drops to 0%
then it rinses and repeats

in a large project with a lot of other canvas drawing it causes the whole browser to hang


Expected results:

This did not happen in previous version.

[Milan Sreckovic [:milan] (needinfo for best results)]

Any chance you could run mozregression tool (http://mozilla.github.io/mozregression/quickstart.html) and find out when this started happening?  Also, a graphics section of about:support would be useful.

... Also, Merry Christmas and a happy new year ;)

Comment 5

[radio]

probably rude and doesn't really solve anything, 
but toggling layout.css.servo.enabled to false, stooped my problems for now.

That's really good info, thanks!

Comment 7

[Emilio Cobos Álvarez (:emilio)]

So, I took a profile of this, and there's definitely a bunch of overhead due to stylo. I don't think it'd cause the browser to hang on its own but:

 * Stylo profile: https://perfht.ml/2CgcBa7
 * Non-Stylo profile: https://perfht.ml/2CdTNsb

So, either we're doing the style resolution for canvas too often, or we're doing too much work there.

Hiro, you implemented this in bug 1324700, mind taking a look? Looks like there's a bunch of stupid stuff going on, from stuff not getting inlined like length serialisation, to tons of allocation or what not.

Comment 8

[Hiroyuki Ikezoe (:hiro)]

Taking.  Though the test case is much slower than non-stylo on Firefox 57, but it's not so different on nightly.
