MacBook Pro 2011 early
Graphics: Intel HD Graphics 3000 384 MB
Plexamp 1.0.4
None of the visualizers except for Pulsar Joy and Trails are working.

Huh, weird… I don’t have a system to test with, but if you visit e.g. [http://editor.thebookofshaders.com](http://editor.thebookofshaders.com) in Chrome, does it work? Any errors in Application.log?

Visiting [http://editor.thebookofshaders.com/](http://editor.thebookofshaders.com/) in chromium, clicking “Test” → nothing
Testing in Firefox → works, colors changing

@syncopation ~ interesting! Actually, does [https://get.webgl.org](https://get.webgl.org) work in Chromium? Not sure why Firefox would support it, but Chrome wouldn’t…
Pulsar Joy and Trails both use Canvas technology, whereas the others use WebGL.

[https://get.webgl.org/](https://get.webgl.org/)
✓ Firefox
✓ Safari
⨉ Chromium: Hmm. While your browser seems to support WebGL, it is disabled or unavailable. If possible, please ensure that you are running the latest drivers for your video card.
Indeed, Pulsar Joy and Trails both working fine while the other viz are broken.
Btw the broken waveform issue is resolved, the song in question just loaded fine. Waveform shows as expected.

@syncopation ~ doing a [Google search](https://www.google.com/search?client=safari&rls=en&q=chrome+2011+macbook+pro+webgl&ie=UTF-8&oe=UTF-8) seems to indicate there are issues, unfortunately.

ouch :s
After [enabling WebGL](https://www.santoshsrinivas.com/enable-webgl-on-chrome-on-a-macbook-pro-2011/) in chromium,
- [https://get.webgl.org/](https://get.webgl.org/) now says “Your browser supports WebGL”
- [http://editor.thebookofshaders.com/](http://editor.thebookofshaders.com/) also works
what a joy.
Is PlexAmp based on chromium and do flags have to be enabled there as well? Not sure I understand the implications of this finding yet.
[Chromium 644091](https://bugs.chromium.org/p/chromium/issues/detail?id=644091) does not look to great. Assigned since 1 1/2 years.

It is based on Chromium, but I’m not sure it’s possible for you to modify the flags locally over there. It looks like we’d have to add support for that via some presumably advanced setting.

Follow up: Chromium bug [644091](https://bugs.chromium.org/p/chromium/issues/detail?id=644091) has been set to dupe of [719257](https://bugs.chromium.org/p/chromium/issues/detail?id=719257).
The good news: 719257 has been fixed in oct 2018.
The bad news: from what I understand HD 3000 has been blacklisted and will still not work (although not tested, and unsure if I got that correctly).
Sidenote: Should there be a changelog for Plexamp somewhere? Didn’t find it in the Announcements section.
