Re: [Public WebGL] EXT_disjoint_timer_query disabled



I just learned yesterday that Site Isolation has successfully shipped on desktop platforms. We'll proceed with re-enabling EXT_disjoint_timer_query there.

Hi all,

Was just reading that site isolation is live in Chrome: https://arstechnica.com/information-technology/2018/07/chrome-enables-site-isolation-to-blunt-the-threat-of-spectre-attacks/
But the GPU timer is still unavailable any idea of an ETA?

And any news when it will be back in Firefox?

WebGL is a great concept but was coded by a group of people who never
tried to create a real world application with it.

The fact that you can not compile shaders in the background is a major
design flaw and has not been addressed for years because nobody really
seems to care.

Now we cannot time our shaders anymore, which makes it nearly
impossible for some of us to ship our applications. If some of you
would care, there would be ways to enable this again to users, like
showing a dialog and let the user decide to enable this extension or
not per application.

If Microsoft has a security flaw in their graphics subsystem, would
they disable the whole graphics subsystem ? No, they would find a
solution because their business depends on it.

Google just does not care. We will remember.
